Question

How much heat is gained by 1.25 grams of ice?

Answer 1

Heat gained by 1.25 grams of ice is 250 joules

Step-by-step 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.
