What can you say about δu, q and w for the following processess? (a) a chemical reaction occurs irreversibly in a well-insulated, rigid bomb. there is an increase in the number of mols such that pressure increases considerably. ( take the bomb as your system) (b) one kmol of an ideal gas (cpm=30kj/kmol∙k),

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
