Question | Answer |
What is the definition of a Liquid | It takes up space of its container. Its has fairy content volumes. Particles move faster the a solid particles but slower then gas particles |
What is the definition of a Solid | The shape and volume of a solid never changes. The particles vibrate they do not move far apart. Kentic energy is every low that causes the particles to stay together |
What is the definition of a gas | Expands to full empty container, both volume and shape can change.The particles vibrate,rotate and move past each other. Its particles move faster then any of the other three states |
Why do most thunderstorms occur on humid days | The heat of the sun causes the water to change its state into a vapour or a gas causing it to create a thunder cloud |
What are three examples of convection in the environment | Lake winds
land breeze
Thunder clouds |
Name two things that absorb the suns radiant energy | Dark colours
Tar (used on roads) |
What are two things in your home that give off radiant energy,how can you tell | Candles and Light bulls because the produce light and heat |
Are these statements true or false, if false why are they and how can you make them true
a:Particles of a cold object are not moving
b:the particles that make up matter are invisible
c:Energy moves from a colder object to a warmer object | a: False Particles in a cold object are moving very slowly
b:True
c:false Energy moves from a warmer object to a colder object |
How does geothermal energy help form rocks | it melts big rocks and small rocks and collides them together thus creating a new rock with new layers |
Name two kinds of rocks formed by conduction of energy | Igneous and medophic rocks |
Were is the best place to find a igneous rock and why | by a volcano because when lavas cools and hardens it creates igneous |
Why does a frozen juice box melt in your lunch bag | the warm energy (lunch box) energy moves into the juice box (cold energy) |
Can we control the rate of thermal energy | yes we can by technology like a microwave |
What is the definition of kinetic energy | Kinetic energy is when a object does not move on its own but the particles are always moving for example a ruler |
What is the definition of temperature | Temperature is the mass of average kinetic particles |
which of the three states of matter in a list has the
a:most kinetic energy
b:less Kinetic energy
c:least kinetic Energy | answers:
a: Gas
b: Liquid
c: Solid |
