For a cyclic process,what is true?

For the reaction,$2Cl_{(g)} \to Cl_{2_{(g)}}$,what are the signs of $\Delta H$ and $\Delta S$?

$A$ certain mass of a gas was brought from state $A$ to $B$ by following three different paths, namely $1$, $2$ and $3$, respectively. Which of the following relations is correct for the work done?

An ice cube placed in an ideal thermos flask represents a/an ...... system.

Calculate work done if $1 \ mole$ of an ideal gas expands isothermally from $2 \ dm^3$ to $2.8 \ dm^3$ against constant external pressure $1 \ atm$. (in $J$)
