What increases as the temperature of a solid object rises?A. thermal energy

B. potential energy

C. volume

D. mass

Answers

answer is thermal energy
A. Thermal energy
Thermal energy is heat energy, therefore the hotter a solid is the more thermal energy it has.

C. Volume
When an object gets hotter, it expands. This is becuase the particles vibrate more and so are less compact.

What kind of heat transfer primarily occurs within a pot of water that is heated on the stove?A. radiation
B. conduction
C. convection
D. temperature

Answers

Answer:

The kind of heat transfer that primarily occurs within a pot of water that is heated on the stove is convection

Explanation:

We will start by defining all the terminologies, then afterward, we will fish out the answer.

RADIATION : Radiation can be define as the transmission of energy  in the form of waves or particles through space or through a material medium, the earth gets the heat of the sun through the process known as radiation.

CONDUCTION :This is the transfer of heat from one object to another object with different temperature when the come in contact with one another.

CONVECTION : Convection can be defined as the transfer of heat from one place to another  by movement of fluids.

TEMPERATURE: This can simply be defined as the degree of hotness or coldness of an object.

From the above definition, we can deduce that the kind of heat transfer that primarily occurs within a pot of water that is heated on the stove is convection

convection. As the water molecules are being heated up at bottom, the molecules with less heat energy then move to take their place. By doing this all the water should reach an equal temperature.

The equation V=tk is used to describe the relationship between the volume of a gas tank and the time required to fill it . Is the symbol "K" a proportionally constant?

Answers

Answer:

The symbol 'K' is a proportionality constant because it shows the direct relationship between the gas tank volume, v, and the time required, t, to fill.

It  is also the constant product of the ratio of the gas tank volume to the time required to fill it.
