If the gas is heated, the particles will move faster as they gain more energy. Bob cools down some gas at the plant. When he does this, the gas particles move slower and gain energy or lose energy.?
lose energy.

Air in the troposphere is warmer closer to Earths surface. When you are driving down a mountain you will notice the temperature decreases or increases?

A: less

Question: Nations that have more industry produce more hazardous waste. When you have a lot of factories in an area the level of trash will increase or decrease?

*Question*
At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. A particle that is in the desert is likely faster or slower compared to one in the arctic?
**Answer**
faster

It would be hard to get a big chunk of chocolate to dissolve in your milk or hot water. Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk.

To make the chips melt more slowly, Shane will use chips that are bigger or smaller?
bigger
