What is specific heat defined?

specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree.

What is specific heat answer?

The energy required to heat something is proportional to the mass and temperature change of the material. Specific heat is the amount of heat per unit mass needed to increase the temperature of a material by one degree Celsius or Kelvin.

What is specific heat in chemistry?

The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1oC. The units for specific heat can either be joules per gram per degree (J/goC) or calories per gram per degree (cal/goC).

What is latent heat Class 11?

Basically latent heat is the heat by which phase of material got changed but the temperature remains constant. It is the heat required to change the phase without changing the temperature. Whereas the heat which is required to change the phase due to temperature change is known as sensible heat.

What is the definition of specific latent heat of fusion?

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. Each substance has two specific latent heats: latent heat of fusion (the amount of energy needed to freeze or melt the substance at its melting point)

What is the relationship between specific heat and temperature?

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat.

What does it mean to have a higher specific heat?

Specific heat is a measure of heat required to raise the temperature of 1 gram of water 1°C. Water has a high heat capacity, meaning that it changes temperature slowly after gaining or losing energy. In fact, water has the second highest specific heat capacity of any known substance after ammonia.
