Acontainer holding 1.5 moles [mol] of oxygen (formula: upper o2, molecular weight equals=32 grams per mole [g/mol]) at a pressure of 2.5 atmospheres [atm] and a temperature of 310 kelvins [k] is heated to 410 kelvins [k], while maintaining constant amount and volume. what is the new pressure inside the container in units of pascals [pa]?

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

With increases in magnification, which of the following occur? a. the field of view decreases. b. the ambient illumination decreases. c. the larger parts can be measured. d. the eyepiece must be raised.
