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 be2.76J·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 heatQthat was needed for this temperature change. Your equation should contain only symbols. Be sure you define each symbol.

Answer:

Q=m*c*ΔT=50674.7 Joules

Explanation:

By the definition described, the specific heat c is defined like this:

[tex]c=\frac{Q}{m*\Delta T}[/tex]

Where Q is the heat needed to change the temperature T of a mass m. So, multiplying both sides of the equation by m*ΔT we obtain

[tex]Q=m*c*ΔT[/tex]

Then, we just substitute with the quantities and multiply them.
