A substance with a high specific heat:

Is always extremely hot.

Requires a lot of energy to become hot.

Is not heavy.

fluctuate wildly

The picture shows two completely identical mason jars. They're both filled with the same gas, only one of them has more in it (more molecules). What can you say about the pressures of both jars?

P₁ > P₂(greater pressure in jar 1)

P₁< P₂ (greater pressure in jar 2)

P₁ = P₂ (same pressure in both)

800 J

1600 J

-800 J

-1600 J

How does a refrigerator work?

Moves heat from inside the fridge to the room

Blows cold air into the fridge

Uses convection cells

It generates cold air

A steady force pushes in the piston
of a well-insulated cylinder. In this
process, the temperature of the gas

Increases

Stays the same

Decreases

10.

Warm air rises and the cool air sinks demonstrates this type of heat transfer.

conduction

convection

radiation

Insolation

11.

What is latent heat?

Heat that doesn’t move from high temperature to low temperature, also known as “lazy heat.”

The heat required to move an object from its “latent” position.

The heat required to convert the state of matter of a substance without changing its temperature.

Heat that does not move unless acted upon by an outside source.

12.

A substance of mass 2.0 kilograms is originally in the solid state. The graph below represents the temperature of the substance as heat is added to it. During which interval is the average kinetic energy of the molecules of the substance unchanged?

13.

Absolute zero temperature is taken as

(a) – 273°C

(b) 273°C

(d) – 373°C.

14.

For an adiabatic process, which of the following statements is correct?

a. Work, heat, and internal energy all undergo changes.

b. Work and heat balance each other, so that there is no change in internal energy.

c. No energy is transferred as heat; internal energy change is due to work.

d. No work is done; internal energy change is due to heat.

15.

During phase change ____________________ does not change.

pressure

temperature

work

volume

16.

Rapidly inflating of balloon under a pumping machine.

adiabatic

isovolumetric

isochoric

Isothermal

17.

Jordan places a hot spoon into a container of ice cream. How does this help him scoop out the ice cream?

The coolness from the ice cream is conducted to the spoon making it easier to scoop out.

The coolness from the ice cream is radiated to the spoon making it easier to scoop out.

The warmth of the spoon is conducted to the ice cream making it easier to scoop out.

The warmth of the spoon is radiated to the ice cream making it easier to scoop out.

18.

From lowest entropy to highest entropy, the states of matter go in this order:

solid -> liquid -> gas -> plasma

plasma -> gas -> liquid -> solid

gas -> plasma -> liquid -> solid

solid -> liquid -> plasma -> gas

It depends on the temperature of the object

19.

0th law of thermodynamics

1st law of thermodynamics

2nd law of thermodynamics

3rd law of thermodynamics

20.
