Question

find the amount needed to raise the temperature of 5.00g of a substance from 20.0 celsius to 30.0 celsius if the specific heat of the substance is 2.01 j/g celsius

Answer 1

Specific heat is the amount of heat needed to raise the temperature of 1 g of the substance by 1 degree.

The equation you can use is q = mC∆T

q = heat = ?

m = mass = 5.00 g

C = 2.01 J/gº

∆T = change in temperature = 10.0º

q = (5.00 g)(2.01 J/gº)(10.0º)

q = 101 J (3 sig. figs.)
