Answer:
86.735 kJ
Explanation:
Simply multiply the change in temperature by the Ccal;
(36.6 - 20.0)×5.225 = 86.735
oxidisation.

displacement.
chemical decomposition reaction.
neutralisation reaction.
chain reaction.
chemical action.
reducing.
Answer:
Explanation:
Hello there!
In this case, given the T-V variation, we understand it is possible to apply the Charles' law as shown below:
Thus, since we are interested in the initial temperature, we can solve for T1, plug in the volumes and use T2 in kelvins:
Best regards!
Answer:
Potential energy
Explanation:
A mountain climber at the peak of a mountain has potential energy.
The potential energy of a body is stored energy in a body. It is function of mass and position of the body.
Mathematically;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
