Answer: The soil will be warmer than the water.
Explanation:
The heat (thermal energy) absorbed can be found using the following equation:
Where:
is the heat
is the mass of the element
is the specific heat capacity of the material.
is the variation in temperature
<u>In the case of soil we have:</u>
(1)
Where:
<u>In the case of water we have:</u>
(2)
Where:
Isolating from both equations:
(3)
(4)
(5)
(6)
Comparing (4) and (6) we can find the soil will be warmer than the water.
Answer:
are chemical processes and not nuclear processes. Nuclear reactions do indeed occur in the human body, but the body does not use them. Nuclear reactions can lead to chemical damage, which the body may notice and try to fix.
The total heat that is needed by the water to get converted to steam is calculated below through the equation,
H = (Hv)(n)
where H is the heat, Hv is the heat of vaporization (40.67 kJ/mol), and n is the number of mols. Substituting the known values,
H = (40.66 kJ/mol)(1.5 mol) = 60.99 kJ
Calculating for the time,
t = (60990 J) / (24 J/s)
t = 2541.25 s
Answer: 2541.25 s or approximately 42.35 minutes
