Sagot :

Answer:

Heat  gained by 1.25 grams of ice is 250 joules

Explanation:

As we know

[tex]Q = mc\Delta[/tex]T

Where

[tex]\Delta[/tex]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,

[tex]\Delta[/tex]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 -

[tex]Q = 1.25 * 2.0 * 100\\Q = 250[/tex]Joules.
