The specific heat of ice is 0.48 cal/g $\circ$ C.How much heat will it take to raise the temperature of 10 g of ice from -30 $\circ$ C to -20 $\circ$ C?

Question

Quizplus · Accepted Answer

The formula to calculate the heat energy required to raise the temperature of a substance is:

Q = m x c x ΔT

Where Q = heat energy in calories, m = mass of the substance in grams, c = specific heat of the substance in cal/g°C, and ΔT = change in temperature in °C.

Substituting the given values, we get:

Q = 10 g x 0.48 cal/g°C x (20°C - (-30°C))

Q = 10 g x 0.48 cal/g°C x 50°C

Q = 240 cal

Therefore, the heat energy required to raise the temperature of 10 g of ice from -30°C to -20°C is 240 cal, which is option C.
