The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The heat capacity of a certain substance has been measured to be 1.33J·g°C. Suppose 287.g of the substance are heated until the temperature of the sample has changed by 38.6°C.

Respuesta :

The heat required  to raise the temperature of 287.g of the substance by 38.6°C is 14,734 J.

What is specific heat capacity of a substance?

The specific heat capacity of a substance is the amount of heat required to raise the unit mass of the substance by one degree. The symbol for specific heat capacity of a substance is c.

Specific heat capacity, c = H/mΔT

Heat required = mcΔT

The heat required by the substance = 1.33 * 287 * 38.6

The heat required by the substance = 14,734 J

Therefore, the heat required is determined from the specific heat, mass and temperature change.
