0.12 J/kg . K
Explanation:
Given parameters:
Mass of metal = 20g
Quantity of energy = 30J
Temperature = 12.5K
Unknown:
specific heat = ?
Solution:
The specific heat of a substance is the amount of heat required to raise the temperature of a 1g of the substance by 1K
It is given as:
C = 
input the parameters:
C = 
= 0.12 J/kg . K

Answer: Wind speed and air temperature.
Wind chill factor is a factor which measures the loss of heat from the body due to the effect of low temperature air to which the body is exposed. This heat loss can be calculated by combination of factors like wind speed and air temperature that can be used to converted to a wind chill equivalent temperature or wind chill temperature. Higher the wind speed more will be the heat loss and lower the air temperature faster will be the cooling of the body. Therefore, wind speed and air temperature are considered for calculating the wind chill factor.
