In the temperature range 310 k to 330 k, the pressure p of a certain nonideal gas is related to volume v and temperature t by p= (24.9 j/k)\frac{t}{v} t v - (0.00662 j/k ) \frac{t^2}{v} t 2 v . how much work is done by the gas if its temperature is raised from 315 k to 325 k while the pressure is held constant?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

What component of earth’s atmosphere exists entirely as a result of photosynthesis?
