Question

How much heat is gained by 1.25 grams of ice?

Answer 1

Answer:

Heat  gained by 1.25 grams of ice is 250 joules

Explanation:

As we know

$Q = mc\Delta$T

Where

$\Delta$T is the change in temperature

Water freezes at 273.15 K/0 degree Celsius, and it boils at 373.15 K/00 degree Celsius,

$\Delta$T  

m is the mass in grams

c is the specific heat of water (ice) = 2.05 joules/gram

Substituting the given values, we get -

$Q = 1.25 * 2.0 * 100\\Q = 250$Joules.
