Question
The heat that is transferred between the sun and the earth is transferred by Radiation Conduction .Convection Both 2 & 3 1, 2, & 3 The coefficient of linear expansion for Cu is 5.1 Times 10^-5 K^-1. What is the final length of a piece of Aluminum whose original length is 3.27 m, and original temperature is 263 K. if the final temperature up equation, you do no need to plug in the numbers into your calculator.) What is the quantity of heat needed to raise 3.28 kg of Water at 37.2 C degree to 72.8 C degree? C = 4190 J/kg K, L_f = 3.34 Times 10^5 J/kg. L = 2.26 Times 10^6 J/kg (Set up the equation, you do no need to plug in the numbers into your calculator.)Explanation / Answer
the heat transformation between sun and earth is by 1.Radiation
so the answer is 1) Radiation
----------------------------------------------------------
final length is L2 = L1 (1 + alpha*dT)
L2 = 3.27*(1 + (5.1*10^-5*(299-263))) = 3.27600372 m
-------------------------------------
required heat is Q = m*C*dT = 3.28*4190*(72.8-37.2) = 489257.91 J
