Gas is trapped inside of a cell with volume 140 m3. the gas exerts 7600 pa of pressure against the walls of the cell. a machine then expands the cell and gives off 490 kj of heat to the gas during the process. if the internal energy changed by 140 kj, what is the final volume of the cell? assume the pressure stays constant.
a. 57 m3
b. 94 m3
c. 660 m3
d. 220 m3
e. 190 m3

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
