When the bulb of a constant-volume gas thermometer is placed in a beaker of boiling water at 100 oC, the pressure of the gas is 229 mmHg . When the bulb is moved to an ice-salt mixture, the pressure of the gas drops to 161 mmHg .
Assuming ideal behavior, what is the Celsius temperature of the ice-salt mixture?
A 0.03 kg (lead) bullethits a steel plate and melts and splatters on impact. Assuming that the bullet recieves 80% of the collision energy, at what minimium speed must it travel to melt on impact? How is this soved without knowing what the bullet is ..
