## Why the less amount of energy is required to convert ice into water than to convert the same mass of water into steam?

When ice (a solid) melts, it turns into water (a liquid); this is called fusion. When water (a liquid) boils, it turns into steam (a gas); this is called vaporisation. … A solid substance at its melting point has less energy than the same mass of the substance when it is a liquid at the same temperature.

## How do we calculate energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

## How do you calculate energy released per gram?

Calculate the energy released per gram of fuel using the following equation.
1. Energy given out = mass of water × 4.2 × temperature change.
2. Energy measured in joules, J.
3. 4.2 is the specific heat capacity of water, J/g°C.
4. Temperature change = temperature of water after heating – temperature of water before heating.
