1. What is the temperature at which this substance condenses from a gas to a liquid? 2. Between what two temperatures is this substance in the liquid phase?

3. Clearly label where on the diagram the substance is a solid.

4. If you were heating this substance as it was melting, what is the heat energy doing at that time?

5. What phase of matter does the diagram represent?

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

thats how its supposed to be

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
