Ginormous December 2024 Final (no naming/formulas)

Front

What is convection?

Back

Convection is the primary way heat travels through liquids and gases.

Front

Why is sand at the beach hotter than water?

Back

Sand has a lower specific heat than water.

Front

What is the specific heat capacity of iron if a 15.75-g piece absorbs 1086.75 joules of heat and its temperature changes from 25°C to 175°C?

Back

0.46 J/g°C

Front

How much energy is needed to raise the temperature of 5.0 grams of lead from 25°C to 35°C? (specific heat of lead = 0.129 J/(g•°C))

Back

6.45 Joules

Front

What is a conductor of heat?

Back

A material that allows heat to pass through it easily.

Front

What is an insulator?

Back

A material that resists the flow of heat.

Front

Define specific heat capacity.

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1°C.

Front

What is the formula for calculating heat energy?

Back

Q = mcΔT, where Q is heat energy, m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact no longer transfer heat to each other.
