Which statement relates most directly to the second law?
2 answers:
Statement three i do believe
Answer: Option (2) is the correct answer.
Explanation:
According to second law of thermodynamics, all the energy of a system cannot be converted into useful work because some amount of energy will be lost.
For example, a machine will never convert its energy into 100% work as some of the energy of machine will be lost into the atmosphere.
Therefore, we can conclude that the statement some thermal energy is lost and some is used to do work, relates most directly to the second law.

37.34372 kg
Explanation:
m = Mass
= Change in temperature
1 denotes water
2 denotes copper
c = Heat capacity
Heat is given by
In this case the heat transfer will be equal
Mass of copper block is 37.34372 kg
Answer:
F = 1,875 N
Explanation:
force=
∆H = m∆V
where ∆H ----> change in momentum.
( final momentum - initial momentum )
and ∆V ----> change in velocity
( final velocity - initial velocity )
and m ----> is mass
then f =
= 1,875 N
P=M(mass)G(Gravity)H(Height)
Gravity=9.8
M=1.5 G=9.8 H=35
so multiply all
=514.5 potential energy
