Heat that occurs when the particles of a substance carry thermal energy as they move from one place to another in a curricular mouton
Heat that occurs when there are no particles to carry the energy
Heat that occurs when the particles of a substance bump into each other
Heat that usually occurs in liquids and gases
Heat that usually occurs in solids
Heat that can travel through space from the sun to the earth
This term describes the ability to work
What scientific term is used to measure temperature?
Which temperature scale do most scientists use?
Do most substances expand or contract when heated?
There are 2 cups of water -- 1 is 14 degrees Celsius and the other is 100 degrees Celsius. Which one has more thermal energy?
The one with 100 degrees Celsius because it is hotter. The amount of thermal energy in a substance depends on the temperature and mass of that substance.
______ is the ability to do work
________, also called "stored energy" is the energy that an object or substance has of its position or condition.
______ is the energy that an object or substance has because of its motion
_____ is the total kinetic energy of the particles in a substance
The amount of a substance's thermal energy depends on the temperature and ______ of that substance.
The measure of the average kinetic energy of the particles in a substance is called _______
An instrument that measures temperature is a _____
The _____ scale is usually used by scientists to measure temperature. The scale is based on 0 degrees as the freezing point and 100 degrees as the boiling point.
The attraction between the particles of a substance depends on the ______ at which its particles move
When the temperature of a substance increases, the _____ of its particles also increases
The faster the particles move, the _____ attraction there is between the particles
A ______ has particles that vibrate back and forth. It has great attraction between the particles
A _______ has particles that move faster than a solid. It has less attraction between the particles than a solid.
A ____ has particles that move rapidly and cover great distances. It has little attraction between its particles.
When cooled, a substance ______ thermal energy.
Sometimes particles in a substance mov faster and occupy a larger space but do not change to another state of matter. This is known as ________
Almost every substance _____ when heated and ____contracts when cooled.
Expands when heated -
Contracts when cooled
The amount of thermal energy needed to raise the temperature of 1 g of water 1 degree Celsius is called a ______
What are examples of how thermal expansion affects every day life?
-movement of liquid in liquid thermometers
- design of spaces between sections of sidewalks, bridges and roads for expansion
Why do metal object get warmer than plastic objects?
-some substance heat or cool more easily than others
-metal can store more heat than plastic
True or False:
Heat flows from cooler objects to warmer objects
True or False:
As you increase the temperature of a substance the speed of its particles decreases
True or False:
When matter is heated it always changes to another state
True or False:
