1. Suppose the temperature of a liquid is 350 Kelvins. What is this in Fahrenheit? 2. A mass m=0.6 kg is initially moving at 0.4 m/s on a frictionless air track toward a spring (k= 900 N/m) attached to the end. The mass compresses the spring, stops then recoils at -0.4 m/s. How much was the spring compressed? 3. What is the rms speed of a water molecule in a room whose temperature is 20 degrees C? (water is H 2O where H=1 u. O= 16 u) 4. A gas is in a cylinder with a piston free to move while the pressure is constant at 1 atmosphere When 1250 kilocal of heat is added, the volume increases by 6.2 m^3. What is the change in internal energy of the gas in Joules? 5. A person in a campground yells and a person 1.5 m away hears It as an 85 db sound. Another person in a nearby parking lot is 800 m away. What sound level does this person hear?Explanation / Answer
