Thermo review c1

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What happens to heat in an exothermic reaction?

Back

In an exothermic reaction, heat is released into the surroundings.

Front

How do you calculate specific heat?

Back

Specific heat (c) can be calculated using the formula: c = Q / (m * ΔT), where Q is the heat added, m is the mass, and ΔT is the change in temperature.

Front

What does a high specific heat indicate?

Back

A high specific heat means that a substance requires more energy to change its temperature.

Front

If 800 cal is used to heat 40g of water, what is the temperature change?

Back

The temperature change can be calculated using the formula: ΔT = Q / (m * c). For water, c = 1 cal/g°C.

Front

What is the specific heat of water?

Back

The specific heat of water is 1 cal/g°C.

Front

What is the formula for calculating heat energy?

Back

The formula for calculating heat energy is Q = m * c * ΔT.

Front

What does it mean if a reaction is thermodynamically favorable?

Back

A thermodynamically favorable reaction is one that occurs spontaneously under given conditions.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

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.
