What is the change in internal energy of a system if the surroundings (a) transfer $235 \mathrm{J}$ of heat and $128 \mathrm{J}$ of work to the system; (b) absorb $145 \mathrm{J}$ of heat from the system while doing $98 \mathrm{J}$ of work on the system; (c) exchange no heat, but receive $1.07 \mathrm{k}$ ] of work from the system?
