specific heat and calorimeter

Front

What is specific heat?

Back

Specific heat is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1ºC.

Front

Why is water used as a coolant in automobiles?

Back

Water has a relatively large specific heat, allowing it to store a great deal of thermal energy.

Front

What does a calorimeter measure?

Back

A calorimeter measures the energy change in a reaction.

Front

How do you calculate temperature change?

Back

Temperature change is calculated as final temperature - initial temperature.

Front

When is heat considered a positive quantity in calorimetry?

Back

Heat is positive when the system absorbs heat.

Front

What is the role of the thermometer in a calorimeter?

Back

The thermometer measures the temperature change during a reaction.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the relationship between specific heat and temperature change?

Back

The specific heat of a substance determines how much its temperature will change when a certain amount of energy is added or removed.

Front

What is the formula for calculating heat energy?

Back

The formula is 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.
