Question

If the snowman's mass is originally 357.8 grams and is still a solid at zero degrees

Celsius, how much energy(cal) will the sun need to add to completely melt the
snowman to all liquid water? (still liquid but at zero C). (Write down your answer, you
may need it in future questions)
OA) 4.47 cal
B) 193200 cal
C) 28600 cal
D) 0.67 cal

Answer 1

The sun does not need to add any energy to melt the snowman.

Step-by-step explanation:

To calculate the amount of energy needed to completely melt the snowman, we need to use the equation Q = mcΔT, where Q is the energy required, m is the mass of the snowman, c is the specific heat capacity of ice or water, and ΔT is the change in temperature.

Since the snowman is already at 0 degrees Celsius, ΔT = 0 - 0 = 0.

The specific heat capacity of ice is 2.09 cal/g°C, so we can substitute the values into the equation:

Q = 357.8 g * 2.09 cal/g°C * 0°C = 0 cal.

Therefore, the sun does not need to add any energy to melt the snowman since it is already at 0 degrees Celsius.
