What is the process of solid to gas?
Sublimation.
What process is water changing into ice?
Freezing.
During the day, why is the sand much hotter that the water at the beach?
Water increases its temperature less than sand, and water retains heat better.
How do we replenish our energy?
Through food (the nutrients react in our cells with the oxygen in the air, creating thermal energy).
The volume of a body (whether it's solid, liquid or gas) increases due to a rise in ____________.
Temperature.
Thermal energy is ________ when a body changes from liquid to gas.
Absorbed or gained
Crumble: to break into small pieces
Which American franchise is named after this word? What product do they sell?
CRUMBL COOKIES. COOKIES.
DAILY DOUBLE: The water in small children's pool is a higher temperature than the water in large pools for adults. Why does this happen if they receive the same amount of sun?
Even though both pools receive the same amount of sun, the adult's pool has a greater amount of water, meaning that it requires more energy to raise the temperature.
True or false: The environment around us usually has a higher temperature than our internal body temperature.
False. The environment around us is usually at a lower temperature than our internal body temperature.
Which expands more? why? Solids, liquids or gases.
Gases expand a lot more because their particles move more freely.
What is the process of gas to solid?
Reverse-sublimation/deposition.
What is the symbol for energy transferred in the form of heat?
Temperature increase is directly ____________ to the heat input.
Proportional (the same size/amount).
Name three energy sources that provide us with thermal energy for heating hot water
Gas fired, geothermal energy, solar thermal panels, and electric radiators.
Do solids expand? (yes/no)
Yes, but very little.
Thermal energy is ________ in the process of freezing.
True or false: Water increases temperature less than metal.
True.
Three times the amount of heat, ___________ the temperature increase.
Three times.
Should we wear less clothing in order to minimize energy loss? (yes/no)
No. We wear more clothing (which is insulating) to minimize energy loss.
Which instrument of measurement works on the basis of the expansion of the liquid inside of them
Thermometers. They used mercury/alcohol in a glass tube. When heated, the liquid expanded and the level rised.
When all the water evaporates, the temperature of the vapor increases. What is this referred to as?
Vapor heating
Describe the movement of the particles within a gas.
Move rapidly, spaced out from one another, random motions.
