- (a) For the astronauts in the International Space Station, how does their mass and weight compare to what they were when they were on the surface of the Earth? Why? (b) What is temperature? What is heat? (c) How does the 0th Law of Thermodynamics dispute the caloric fluid model of heat in terms of when an object reaches thermal equilibrium?If a lighted match is held beneath a balloon inflated with air, theballoon quickly bursts. If, instead, the lighted match is held beneath a balloon filled with water, the balloon remains intact, evenif the flame comes in contact with the balloon. Explain.
