What is the value of work (w) when a piston of volume 0.2 L expands against an external pressure of 200 kPa to a volume of 3.4 L?
How long would it take for 1.50 mol of water at 100.0 0C to be converted completely into steam if heat were added at a constant rate of 15.0 J/s?
The mass of a golf ball is 45.9 g. If it leaves the tee with a speed of 61.0 m/s, what is its corresponding wavelength?
what is the final temperature of the block after the evaporation of the alcohol? Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at 25'C.
A gaseous reaction occurs at a constant pressure of 50atm and releases 61.5kJ of heat. Before the reaction, the volume of the system was 7.00L. After the reaction, the volume of the system was 2.60L.
