Consider the following reaction:
$CO_{(g)} + 1/2 O_{2_{(g)}} \to CO_{2_{(g)}}$
How are $\Delta E$ and $\Delta H$ related for the reaction?

The change in internal energy of a system depends upon

Fill in the blanks given below:
$(i)$ $A$ system in which the exchange of energy between the system and the surroundings is possible but the exchange of matter is not possible is called a .......
$(ii)$ The total amount of energy, which is the sum of the internal energy of the substance and the product of its pressure and volume, is called .......
$(iii)$ The change in energy that occurs when a chemical reaction is carried out at constant pressure is called .......
$(iv)$ The process of attaining thermal equilibrium between any two heat-conducting substances is known as the ....... law of thermodynamics.

For a phase change$H _2 O ( l ) \underset{1 bar , 0^{\circ} C }{\rightleftharpoons} H _2 O ( s )$

$A$ $5 \, L$ cylinder contains $10 \, mol$ of $O_2$ gas at $27 \, ^\circ C$. Due to a leak,the gas escapes into the atmosphere until the pressure inside the cylinder equals the atmospheric pressure $(1.0 \, atm)$. What is the work done by the gas?

Which of the following is an example of both an intensive property and a state function?
