Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No
Answer:
The liquid decreases in temperature and its particles lose kinetic energy.
Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air

A 3.56 L balloon is compressed to 1.00 L at constant temperature. If the initial pressure in the balloon was 101.3 kPa, what is the final pressure?
An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will happen to it's temperature?
a. It will halve to T/2.
b. It will increase to 3T.
c. It will increase to 2T.
d. It will remain the same.
Answer:
It will be halve of T
Explanation:
V1 = V
T1 = T
V2 = ½V
T2 = x
V1/T1 = V2/T2
V/T = ½V/x
Vx = ½VT
2Vx = VT
2x = T
x = ½T

Answer:
1037.56 mph
Explanation:
We are told the distance around the earth which is the circumference is 40075 km.
Converting to miles gives 24901.451 miles
Formula for speed = distance/time
Time for one rotation is 24 hours.
Thus, speed = 24901.451/24 = 1037.56 mph
On the periodic table, what is a group? For the main groups, what characteristic
do the elements have in common?
Answer:
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Explanation:
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties.
For the main groups, the characteristic do the elements have in common is valence electron configuration and chemical reactivity.
On the periodic table, a group refers to a vertical column of elements that share similar chemical properties. These elements are arranged in such a way that they have the same number of valence electrons, which are the electrons in the outermost energy level (shell) of their atoms. The number of valence electrons is a critical factor in determining the chemical behavior and reactivity of elements, as it governs their ability to form chemical bonds with other elements.
Main group elements, also known as representative elements, are located in the s-block and p-block of the periodic table. These elements are found in Groups 1, 2, and 13 to 18. Each main group is labeled with a number from 1 to 18.
Here are the main characteristics that elements in the same main group (vertical column) have in common:
1. Valence Electron Configuration: Elements in the same main group have identical valence electron configurations. For example, elements in Group 1 (alkali metals) all have one valence electron in their outermost energy level (ns¹), while elements in Group 18 (noble gases) have a full outermost energy level.
2. Chemical Reactivity: Due to their identical valence electron configuration, elements in the same group show similar chemical reactivity. They tend to form similar types of chemical bonds and react similarly with other elements to achieve a more stable electron configuration.
3. Periodic Trends: Main group elements within a group exhibit predictable trends in their physical and chemical properties as you move from the top to the bottom of the group. For example, the atomic radius tends to increase, ionization energy tends to decrease, and metallic character tends to increase as you go down a group.

THE MYSTERY SALT
Imagine that you have a barrel of salt, but you forgot to label it. You know it must be either KNO3, or KCl.
You look at the solubility curves for KNO3 and KCl and you find that at 35 degrees Celsius, 100 g of water can dissolve about 30 g of KNO3, or about 37 g of KCl.
The solubility curves disappear. You only remember the solubility for both salts at 35 degrees Celsius in 100g of water. You know absolutely nothing else about these salts.
You have a scale, a hot plate, a thermometer, empty beakers, and plenty of water. You do NOT have any labeled KNO3 or KCl.
1. What property can you use to determine whether the barrel contains KNO3 or KCl? Hint: Name the property you could use to identify the mystery salt? (1 point)
2. Explain exactly what you would do. Another person should be able to perform your test by following your procedure. Do not bother with why you are doing these steps. Just tell me exactly what to do to perform this test. Hint: Do NOT include any discussion of your results. Save that for #3. (2 points)

Answer:
okay but give me brainliest
Explanation:
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Volcanic flows are called lahars.
