Answer: I believe the answer is A, heat moves from warmer objects to cooler objects. I know for sure it isn’t C or D though so A
The heat is transferred from one object to another as heat moves from warmer objects to cooler objects. The correct option is A.
What is the transfer of heat?There are three ways to transfer heat. They are conduction, convection, and radiation. Heat travels from one body to another body. If the temperature of two objects is different, then the heat travels from higher temperature to lower temperature.
Conduction is the transfer of energy when two objects ate in contact with each other. Convection is a transfer between object and environment. Radiation is when transferred by emission of electromagnetic radiation.
Thus, the correct option is A. Heat moves from warmer objects to cooler objects.

Please write the answer in format below
Answer:
0.95 L
Explanation:
Step 1: Given data
Concentration of the Mg(NO₃)₂ solution (C): 0.32 M (0.32 mol/L)
Mass of Mg(NO₃)₂ (solute): 45 g
Step 2: Calculate the moles corresponding to 45 g of Mg(NO₃)₂
The molar mass of Mg(NO₃)₂ is 148.33 g/mol.
45 g Mg(NO₃)₂ × 1 mol Mg(NO₃)₂ /148.33 g Mg(NO₃)₂ = 0.303 mol Mg(NO₃)₂
Step 3: Calculate the volume of solution that contains 0.303 moles of Mg(NO₃)₂
The concentration of the solution is 0.32 M, that is, there are 0.32 moles of Mg(NO₃)₂ per liter of solution.
0.303 mol Mg(NO₃)₂ × 1 L Solution / 0.32 mol Mg(NO₃)₂ = 0.95 L

Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

Exxplanation:
Answer:
Although it is possible to have more than one state, it is also possible to have only one state.

What is temperature?
Answer: Temperature is an objective measurement of how hot or cold an object is. It can be measured with a thermometer or a calorimeter. It is a means of determining the internal energy contained within a given system.
Explanation:
Answer:
Temperature is a physical quantity that expresses hot and cold
Explanation:
Temperature is a physical quantity that expresses hot and cold. This is how the air feels and how hot/cold something is. The less tight the atoms are, the hotter something is. The more tight the atoms are, the cooler something is.

Explanation:
1. It can be reshaped by a force. Physical property can be observed and measured without any changes in molecular composition.
2. A physical property is one that can be change without altering the identity of the substance. These set of properties is not concentration dependent they are use to describe matter. Example are: density, solubility, melting point and color and odor. For this case the second option seems to fit the description it can be reshape by force.
