| Question | Answer |
|---|---|
| What are the 3 common temperature scales | Celsius, Fahrenheit, kelvin |
| When scientists think about temperature they are thinking about? | Particles that make up matter Are always in motion and have kinetic energy. Temperature is a measure of the average kinetic energy of the individual particles of an object |
| Most common temp scale used in US | Fahrenheit |
| Fahrenheit- water freezes at? | 32 |
| Fahrenheit- water boils at what temp | 212 |
| Fahrenheit- the interval between freezing and boiling temperatures is divided into how many equal intervals | 180 |
| Temperature scale used most around the word | Celsius |
| Celsius- water freezes at | 0 |
| Celsius-water Boils at | 100 |
| How many degrees Celsius is mommyâs morning dragon breath | 1000 |
| Temperature scale used in physical science | Kelvin |
| Units on a Kelvin scale are the same size as those in the âââ scale | Celsius |
| Absolute 0 at Fahrenheit is | -460 |
| Absolute 0 in Celsius is | -273 |
| Absolute 0 in Kelvin is | 0 |
| Water boils at what temp kelvin | 373 |
| Any temperature on the Kelvin scale can be changed to celsius by adding how many degrees | 273 |
| Why is the number 273 so special | Experiments have led scientists to conclude that -273 celsius is the lowest temperature possible |
| The Kelvin scale is defined so that 0 on the Kelvin scale is? | Absolute 0 |
| What is absolute 0 | Point where no more energy can be removed from matter |
| The total energy of all the particles in a substance is called | Thermal energy |
| Thermal energy is also known as | Internal energy |
| TorF- a large pot of cocoa can have the same temperature as a small cup of cocoa | True |
| TorF- 1 liter of cocoa at 75 degrees fahrenheit has the same thermal energy as 2 liters of 75 degrees Fahrenheit cocoa | False |
| TorF- the more particles a substance has at a given temperature, the more thermal energy it had | True. |
| Besides temperature and the number of particles in a substance, thermal energy also depends on âââ | How the particles are arranged |
| Are thermal energy and temperature the same? Explain | |
| How is the motion of the particles within a substance related to the thermal energy of the substance? | |
| Why are there no negative numbers on the Kelvin scale | Because absolute 0, the lowest temperature possible is defined as zero on the Kelvin scale |
| The movement of thermal energy from a substance at a higher temperature to another at slower temperature is defined as | Heat Heat is thermal energy moving from a warmer object to a cooler object |
| Tor F-matter contains thermal energy not heat | True |
| What are the 3 ways heat can move it be transferred | Conduction, convection and radiation |
| Heat is transferred from one particle of matter to another without the movement of matter itself is the definition of | Conduction - think of how a metal spoon in a pot of water being heated on an electric stove. |
