Calculate the energy required to heat 406.0mg of cyclohexane from 33.5°c to 38.9°c . assume the specific heat capacity of cyclohexane under these conditions is 1.85·j·g−1k−1 . be sure your answer has the correct number of significant digits.

The heat needed to warm 406.0 mg of cyclohexane from 33.5°C to 38.9°C is 209.22 Joules

Explanation:

Where:

Q = heat absorbed or heat lost

c = specific heat of substance

m = Mass of the substance  

ΔT = change in temperature of the substance

We have mass of cyclohexane = m = 406.0 mg = 0.4060 g

( 1 mg =0.001 g)

Specific heat of cyclohexane  = c = 1.85 J/g°CK

ΔT = 38.9°C - 33.5°C = 5.4°C =5.4+273.15 K = 278.55 K

Heat absorbed by the cyclohexane :

The heat needed to warm 406.0 mg of cyclohexane from 33.5°C to 38.9°C is 209.22 Joules

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
