How do you calculate the heat required to raise the temperature?
The specific heat capacity of a substance is the quantity of heat needed to raise the temperature of a unit quantity of the substance by one degree. Calling the amount of heat added Q, which will cause a change in temperature ∆T to a weight of substance W, at a specific heat of material Cp, then Q = w x Cp x ∆T.

1 Answer. 2000 J of heat energy are released.
What is meant by the statement that the specific heat capacity of water is 4200 J kg K?
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
What is thermal conductivity of sand?
Thermal conductivity of Sand is 0.25 W/(m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.
Why does sand heat up more than water?
Sand heated up faster than water because sand is darker than water; dark colored materials will absorb more light. Sand heated up faster than water because sand is a solid and water is a liquid.
