Chemical Interactions I-check 5

Front

What is temperature change?

Back

Temperature change is the difference in temperature between two states, calculated as the final temperature minus the initial temperature.

Front

How do you calculate temperature change?

Back

Temperature change (△T) = Final Temperature - Initial Temperature.

Front

What happens to kinetic energy when warm air is placed in ice water?

Back

Kinetic energy flows from the warm air to the ice, causing the air to cool down.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What happens to the temperature of warm air in ice water?

Back

The temperature of the warm air decreases as it loses heat to the ice water.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles in a substance also increases.

Front

What is the formula for calculating energy used in heating water?

Back

Energy (calories) = mass (grams) × temperature change (°C).

Front

If 50mL of water is heated from 0℃ to 60℃, how much energy is used?

Back

3000 calories.

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is 1 calorie/gram°C.
