What is A?
This is the negative charged particle in an atom.
What is an electron?
What element has 20 protons?
What heat patterns are seen in the weather?
What are convection currents?
True or False. Radiation uses waves instead of particles for heat transference.
What is true?
What is an insulator?
An insulator does not conduct heat.
This is the neutral part of the atom.
What is the neutrons?
How many electrons does argon have?
What is 18?
In convection, what happens to cold and hot air?
Hot air rises, while cool air stays low.
True or False. Radiation is the only form of heat transference that can occur in a vacuum.
What is true?
How does heat transfer from different objects of different temperature?
As we have seen in the zeroth law of thermodynamics, when two objects are placed in contact heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.
What are protons and neutrons?
What is the symbol for Potassium?
What is K?

The electron cloud is when the electrons spin so fast that it looks like a cloud.
How many neutrons does germanium have?
What is 40?
What are convection currents and how do they effect the Earth?
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology.
What is the law of conservation of energy?
That energy cannot be created or destroyed. It can change form.
How should you design a soup spoon for cooking over a stove?
It should have a handle that is made with an insulator, so you do not burn yourself.
