Thermal energy refers to what in an object?

Only the heat content of the object

Only the kinetic energy of the particles

The energy transferred from the object to its surroundings

The total kinetic and potential energy of all the particles in the object

All objects have this type of energy due to the arrangement of particles. Which is it?

Only kinetic energy

Only potential energy

Both kinetic and potential energy

Electrical energy

Heat transfers between two objects and what exactly happens?

Heat transfers until both objects are the same temperature

Heat always flows from the cooler object to the warmer object

Heat transfers continuously, even when the objects are at the same temperature

Heat stops transferring once the cooler object reaches room temperature

The average kinetic energy of an object changes when it cools, which of the following describes this change?

It increases

It decreases

It stays the same

It becomes constant

Which helps make water vapor happen?

A decrease in thermal energy

A decrease in temperature

Thermal energy, temperature, and a change of state

A constant temperature

Scientific heat is...

The energy transferred from a hot object to a cooler one

The temperature of an object

The average kinetic energy of particles

The energy transferred between two systems at different temperatures

When thermal energy increases, matter......

cools down

melts

contracts

solidifies

Temperature is used to measure what about a substance?

The total amount of thermal energy in the substance

The average kinetic energy of the particles in the substance

The amount of heat in the substance

The potential energy of the particles

The temperature of a substance changes during a change of state, which best describes that change?

It stays the same

It increases

It decreases

It fluctuates

10.

A larger amount of matter requires more thermal energy to heat or cool compared to a smaller amount of the same substance, why?

It has fewer particles and less stored potential energy

It has more particles and more stored potential energy, requiring more energy to change its temperature

It requires more heat transfer to cool down

It has a higher specific heat capacity

11.

When you increase the temperature of a substance, what is expected to happen?

The particles stop moving

The average kinetic energy of the particles increases

The particles lose potential energy

The substance becomes more dense

12.

SI unit of temperature is...

Celsius

Fahrenheit

Kelvin

Joule

13.

0 Kelvin represents....

The freezing point of water

The boiling point of water

The average temperature of the universe

The lowest possible temperature where particles have no kinetic energy

14.

1 degree Celsius in temperature difference is equal to how many kelvins?

10 Kelvin

1 Kelvin

100 Kelvin

0.1 Kelvin

15.

What affects the amount of thermal energy in an object?

Only the temperature of the object

Only the type of matter in the object

The temperature, potential energy, arrangement of particles, and the amount of matter in the object

The arrangement of particles and the type of material only
