Determine how much heat is required to change the temperature of silver by 1 C, if its mass is 1 kg.

The amount of heat that should be required to change the temperature by 1 ° C (1 K) of any substance weighing 1 kg is numerically equal to its specific heat capacity. Those. to heat silver with a mass of 1 kg at 1 ºС, 250 J of heat is required, since its heat capacity is 250 J / (kg * ºС).

Check: Q = С * m * Δt = 250 * 1 * 1 = 250 J (J = J / (kg * ºС) * kg * ºС = J).

Answer: You will need 250 Joules of heat.
