Predictions about the future based on the position of planets is an example of physics biology earth science pseudoscience
Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of pseudoscience.
Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.

What is the temperature change that 725 g of aluminum will undergo when 2.35 x 104
J of thermal energy are added to it?
Answer:
36°C
Explanation:
Given parameters:
Mass of aluminum = 725g
Quantity of heat = 2.35 x 10⁴J
Unknown:
Temperature change = ?
Solution:
To solve this problem, we simply use the expression below:
The quantity of energy is given as:
Q = m C Δt
Q is the quantity of energy
m is the mass
C is the specific heat capacity of aluminum = 0.9J/g°C
Δt is the change in temperature
The unknown is Δt;
Δt = [tex]\frac{Q}{mc}[/tex] = [tex]\frac{2.35 x 10^{4} }{725 x 0.9}[/tex] = 36°C
A gas has a volume of 250.0 liters at 17.0 °C and 3.00 atm of pressure. what volume must the gas be increased for the gas to be at STP conditions?
Answer:
0.706 L (Liters)
Explanation:
P1V1 = P2 V2 3 atm 250.0 mL = 1 atm X
T1 T2 290 K 273 K
706 mL = X
According to the question,
Pressure,
Initial, [tex]P_1 = 3 \ atm[/tex]Final, [tex]P_2 = 1 \ atm[/tex]Temperature,
Initial, [tex]T_1 = 17^{\circ} C[/tex] or, [tex]290 \ K[/tex]Final, [tex]T_2 = 273 \ K[/tex]Volume,
Initial, [tex]V_1 = 250 \ L[/tex]Final, [tex]V_2 = \ ?[/tex]By using the Boyl's and Charl's combination law, we get
→ [tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
or,
→ [tex]V_2 = \frac{P_1 V_1 T_2}{T_1 P_2}[/tex]
By putting the values, we get
→ [tex]= \frac{3\times 250\times 273}{290\times 1}[/tex]
→ [tex]= 706 \ L[/tex]
Thus the aforementioned answer is right.

Substance X has a specific heat capacity that is twice as large as Substance Y. If both samples ended up at the same change in temperature from the same amount of energy added, what is the relationship between the masses of the two samples? Explain.
Answer:
Substance X has a smaller mass
Explanation:
The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.
The specific heat capacity is given as:
C = [tex]\frac{H}{m x change in temperature}[/tex]
We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.
If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass

As the human population grows, the size of cities increases. As cities grow, more land must be cleared to make way for homes, businesses, and roads. Which two events would be likely effects of replacing a forested area with an urban area? A. More air pollution because there are fewer trees to take in carbon dioxide B. Less erosion of soil as plants covering the ground are added to gardens C. Fewer birds and other wildlife because they have fewer places to live D. More trees because of increased solar energy in the area
Answer:1. Introduction
The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise.
The gases forms are: oxidized and reduced forms of carbon (CO2, CO, CH4), of nitrogen (NO2, NO, N2O4, NH3, NH4+), SO2, O3, C6H6 vapours, Hg, volatile phenols, Cl2, etc.
The particulate forms are: PM10 and PM2.5 particulate matter, heavy metals with toxic effect (Pb, Ni, Cd, As), polycyclic aromatic hydrocarbons PAHs, etc.
Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply.

Answer:
A More air pollution because there are fewer trees to take in carbon dioxide
C Fewer birds and other wildlife because they have fewer places to live

What colors are absorbed Best Buy the plant gizmo
Answer:
Yellow and Green
Explanation:
It is not blue the graph shows is isnt blue so the colors that absorbed the worse were green and yellow
Blue and red are the colors that plants can absorb the most. The pigments used for photosynthetic processes, such as chlorophyll in plant cells' chloroplasts, are what absorb particular visible-spectrum light wavelengths.
The energy of specific light wavelengths is absorbed by special pigments in chloroplasts of plant cells, resulting in a chemical chain reaction that is known as the light-dependent process of photosynthesis. The best visible light wavelengths for photosynthesis are in the blue (425–450 nm) and red (600–700 nm) ranges.
Chlorophylls do not absorb light at green and yellow wavelengths, as shown by the extremely low level of light absorption between 500 and 600 nm.

answer: temperature, stp
:P
Answer: temperature, Stp
Explanation:
The calculation for standard temperature and pressure has been referred to as STP.
The mass-volume and volume-mass, has been the measurement of the concentration of the solution.
The mass-volume has been the measurement of mass of sample in the volume of solution. The volume by mass has been the measurement of the volume of solute to mass of solution.
Standard conditionsThe measurement has been performed with the standard conditions of temperature and pressure.
The standard temperature has been 273.5 K and standard pressure has been 1 atm. These temperatures and pressure has been referred to as STP.

How many molecules of carbon dioxide are in 12.2 L of the gas at STP?
Answer:
Converting Between Moles and Liters of a Gas at STP. To convert between moles and the volume of a gas at STP, we will use the factor label method discussed in the first unit. This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L.
Explanation:
One molecule of carbon dioxide at STP has a volume of 22.4 liters . Thus number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.
What is one molecule?A molecule is formed by the combination of same or different kinds of atoms. A number molecules together form a compound. Water, carbon dioxide etc. are compounds.
One mole of a molecule contains 6.022 × 10²³ number of atoms. Similarly, one mole of a compound contains, 6.022 × 10²³ number of molecules.This number is called Avogadro number.
At standard temperature and pressure (STP) that is at 298 K and 1 atm pressure, one mole of any substance carry 22.4 L. Thus number moles of 12.2 L of carbon dioxide is 12.2 / 22.4 = 0.54 moles.
Number of molecules = 0.54 moles × 6.022 × 10²³
= 3.27 × 10²³
Hence, number of molecules of carbon dioxide in 12.2 L is 3.27 × 10²³ molecules.

The best solution to deforestation is to curb the felling of trees by enforcing a series of rules and laws to govern it. Deforestation in the current scenario may have reduced; however, it would be too early to assume. The money-churner nature of forest resources can be tempting enough for deforestation to continue.
