Solution-Calculate the total amount of heat required for

Gold-198 has a half-life of 2.6 days. Determine the mass of a 100 g that would remain after 12 hours.

Sounding rockets are launched to very high altitudes with scientific instruments to measure properties of the upper atmosphere. Consider a 300 kg rocket that generates 4.3 x 104 N of thrust. The rocket is launched straight up from a stand-still and the motor cuts out at an altitude of 10.2 km. a) What is the velocity of the rocket when the motor cuts out? b) What is the rocket's apogee (max height) in kilometres?
How much heat must be removed by a freezer in order to change twenty 60 g sections of water at 0 degrees Celsius to ice at 0 degrees Celsius? (Specific Heat Capacity of Ice: 2.1 x 10^3 J/kgC, Specific Heat Capacity of Water: 4.2 x 10^3 J/kgC, Specific Heat Capacity of Steam: 2.0 x 10^2 J/kgC, Latent Heat of Fusion for Ice/Water/Steam: 3.3. x 10^5 J/kg, Latent Heat of Vapourization for Ice/Water/Steam: 2.3 x 10^6 J/kg)
A duck wants to take a bath and fills the tub with 50.0 L of water at a temperature of 38 degrees Celsius. After taking a phone call from his friend Bob, a lemming, the bath water had cooled by 10.0 degrees Celsius. How much more hot water at 80.0 degrees Celsius must the duck add to return the bath to the desired temperature? (Use information in brackets above if needed.)
