Snow Day Problem Set
Snow Day Problem Set:
Problems from Stair Lab
1. A 100 lb (2.12 lbs = 1kg) man climbs up the stairs slowly, it takes him 200 seconds to climb 4 meters worth of stairs.
a. How much work does he do? (show your work, use units)
b. How much power does it take?(show your work, use units)
2. A 212 lb woman climbs up the stairs quickly. She climbs the 5 meters worth of stairs in 10 seconds.
a. How much work does she do? (show your work, use units)
b. How much power does it take? (show your work, use units)
Problems from Peanut Lab
3. A 2 gram peanut was lit and heated 100g of water. The water started at 20 degrees celsius. The water ended at 40 degrees celsius. The peanut was 1.5 grams after being weighed at the end of the experiment. How many Calories were in each gram of peanut.
4. A honey roasted peanut was lit and heated .05 L of water. The water, initially 25 degrees celsius, was 100 degrees celsius (boiling!!) at the end. The honey roasted peanut weighed 3.0grams at the beginning of the experiment, and 5 minutes later, after it had cooled down, it weighed 1.2 grams. How many Calories are in a honey roasted peanut.

Peanut Lab
PEANUT LAB:
Heat the water. A calorie is the amount of work it takes to heat 1 gram (or 1 mL) of water 1 degree celsius. We will be conducting this lab:
The unit calorie has historically been used in two major alternate definitions that differ by a factor of 1000:
* The small calorie, gram calorie, or calorie (symbol: cal) is the amount of heat (energy) required to raise the temperature of one gram of water by 1 °C.
* The large calorie, kilogram calorie, kilocalorie (symbol: kcal), or Calorie (capital C) is the amount of heat (energy) needed to increase the temperature of one kg of water by 1 °C, exactly 1000 small calories, or about 4.184 kJ.
