Question

How much heat is absorbed from a 56.00 g sample of Mercury when its tempreature change is 289K?

Answer 1

Heat required to raise the temperature of mercury is given as

$Q = ms\Delta T$

here given that

m = 56 g

s = specific heat capacity of mercury = 0.140 J/g C

$\Deta T = 289 k$

now here we have

$Q = 56 * 0.140 * 289$

$Q = 2265.76 J$

so it required 2265.76 J of heat
