Troposphere is much warmer than the Stratosphere.
<u>Explanation:</u>
- The troposphere is the last and the lowest level of the atmosphere, so it is in close contact with the Earth's surface.
- On the other hand, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface.
- So from the above discussion, the troposphere is warmer than the stratosphere.
Answer:
10 million joules or 10,000 KJ
Explanation:
Work= Force x Displacement
convert 5km into meters -5km=5000m
W= 2000N x 5000m
w=10,000,000 Joules
or 10,000KJ
The amount of energy needed to increase the temperature of a substance by
is given by:
where
m is the mass of the substance
is the specific heat capacity of the substance
is the increase of temperature
In our problem,
, while
and the specific heat capacity of iron is
if we plug these numbers in the equation, we find the amount of energy needed:
