It means an object that has a space filled with air on the inside.
hollow
5
It is a three-dimensional shape, having a volume that cannot be calculated using simple equation.
irregular
15
It is a three-dimensional shape, such as a cube or cuboid, having a volume that can be calculated using a simple equation.
regular
5
In this context, an object that has no space filled with air on the inside.
solid
10
Thermal energy is measured in Joules. True or False?
True
15
Heat is a measure of the energy in the particles. true or false?
true
10
Temperature is NOT the same as heat. true or false
true
5
In this context, conserved means the total quantity of something is kept the same.
conserved
5
It means to be made from nothing or from something different.
created
5
destroyed means ceased to exist. True or false?
true
5
In this context, a system is place where an energy change or transfer occurs.
system
10
It is method of thermal energy transfer where more vigorously vibrating particles cause neighboring particles to vibrate by colliding; conduction works best where particles are close together in solids and liquids.
conduction
10
It is a method or thermal energy transfer where more vigorously vibrating particles cause expansion and decrease in density in a liquid or gas; the less dense material then rises because it floats, setting up a convection current.
convection
10
It is a method by which all of a liquid or gas becomes heated through convection; particles flow through the material due to differences in density.
convection current
10
expand it means become smaller. true or false?
false
10
radiation is the method or thermal energy transfer that uses waves and does not depend on particles; occurs through a vacuum, through gases and through transparent solids. true or false?
