Question

How much energy in joules, does it take to heat a 55 gram sample of ice from-10°C to

O-CZ specific heat of ice = 201 Jigº)

Answer 1

Energy needed : Q = 1105.5 J

Further explanation

Given

mass = 55 g

Temperature from -10°C to 0°C

Required

Energy

Solution

Heat can be calculated using the formula:

Q = mc∆T

Q = heat, J

m = mass, g

c = specific heat, joules / g ° C

∆T = temperature difference, ° C / K

Input the value :

Q = 55 g x 2.01 J/g ° C x (0-(-10))

Q = 1105.5 J
