Question

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 2.76J·g°C. Suppose 466.g of the substance are heated until the temperature of the sample has changed by 39.4°C. Write an equation that will let you calculate the heat that was needed for this temperature change. Your equation should contain only symbols.

Answer 1

See below

Step-by-step explanation:

ΔQ = m c T ΔQ = heat required(J) m = mass (g) T = C° temp change

c = heat capacity in J/g-C
