Which subatomic particle is the lightest? (a) neutron (b) proton (c) electron (d) all of the above (obviously not the last one, I guess)

The student measures the actual pressure of the CO2 (g) in the container at 425 K and observes that it is less than the pressure predicted by the ideal gas law. Explain this observation.

1. A food sample is burned in a calorimeter that contains 2000. g of water. The temperature increases from 22.0°C to 44.3 °C. How many Calories does the food sample contain, assuming all of the energy from the food was transferred into the water?

Why doesn't water light on fire? It has all the ingredients except heat! Hydrogen for the flammability factor, oxygen so it can keep burning, and all you need to do is add heat and BOOM you have a flame! 15 pts
