Front

What is the unknown in the problem?

Back

q

Front

Identify the given mass (m) in the problem:

Back

15.75 g

Front

What are the units for specific heat in the formula Q = m c ΔT?

Back

J/g°C

Front

What happens to the force between two charged objects if you triple the magnitude of one charge?

Back

The force increases by 3X.

Front

What happens to the particles if more heat is supplied to the system?

Back

They would speed up.

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 (Q)?

Back

Q = m c ΔT

Front

What does the symbol ΔT represent in the formula Q = m c ΔT?

Back

The change in temperature.

Front

If the mass of a substance is doubled, what happens to the heat energy required to change its temperature?

Back

It also doubles.

Front

What is the relationship between charge and force according to Coulomb's Law?

Back

The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
