How much energy must be absorbed by water with a mass of 0.5 kg in order to raise the temperature from 30°c to 65°C? Water has a specific heat of 4,190 j/kg°C

Q = 67.04 [J]

Explanation:

In order to solve this problem, we must use the following equation of thermal energy, which relates mass to specific heat and temperature change.

where:

Q = thermal energy [J]

m = mass = 0.5 [kg]

Cp = specific heat = 4,190 [J/kg°C]

T2 = final temperature = 65 [C]

T1 = initial temperature = 30 [C]

Now replacing:

Q = 0.5*4.190*(65 - 30)

Q = 67.04 [J]

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
