Answer:
Option A is true
Explanation:
When you are a scientist conducting an experiment on energy transfer .
The reaction in which you measure a large amount of heat energy transfer.
We have to find the units which you should record them in
Energy: It is defined as the capability of doing the work .
When current I is flowing in ampere A V is potential in volt v applied in the experiment and R be resistance in ohm used in experiment for time t in seconds
Then, heat energy ==A-volt=Joule
Heat energy=
Heat energy==Joule
The S.I unit of heat energy is Joules.
Hence, option A is true.

Answer : The final temperature of gas will be, 149 K
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = 1.55 L
= final volume of gas = 753 ml = 0.753 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above formula, we get the final temperature of the gas.
Therefore, the final temperature of gas will be, 149 K
