Who invented the first thermometer and what was it like
what is galio
100
what is the average body temperature
what is 37?

difine the following terms thermal energy,temperature,heat
thermal energy is the total kinetic energy of all the particles in a substance,temperature is a measure of the average kinetic energy of the particles in the substance.Heat is the energy that transfers from a substance whose particles have lower kinetic energy
100
The particle theory of matter
particles are in motion,each substance has unique particles,when heat is added particles move faster when heat is removed particles move slower,particles are held together by attractive forces, all substances are made of tiny particles too small to be seen

explain a bimetallic strip
A bimetallic strip is made of two different metals joined (fused) together,often formed into a coil. when heat is applied to the end one of the metals will expand faster than the other. this will cause the coil to coil tighter or unwind a little.

What was the first thermometer like
It didn't have a scale
200
what is the average room temperature
what is 20?
200
What is the difference between thermal energy and temperature
thermal energy is the total kinetic energy and temperature is the average
200
discribe the particle movement in solide, liquid, gas
solid has little to no room to move and has a fixed shape and volume,liquid able to slip past each other liquids have a fixed shape but no fixed volume, gas lots of room to move but no fixed shape or volume

explain a thermocouple
two wires of different metals are twisted together when heat is applied to one end an electric current is produced
300
How did anders celsius improve the thermometer
what is scale?
300
what is the boiling point of water at sea level
what is 100c ?
300
what is energy
the ability to do work
300
Be able to explain how a cup of hot tea has less thermal energy than a kettle of lukewarm water
beacause it has more mass and so their is more particles
300
what is a recording thermometer
a bimetallic strip that uncoils and coils and has a pen that records the tempature
400
what is the freezing point of water at sea level
what is 0c ?
400
Which direction does thermal energy always flow
from a warmer (higher temperature) object or region to a colder (lower temperature) object or region
400
What is a Infrared thermogram and how would you use it
a camera that shows all the temperature in a image and is used for busted pipe lines and air leakes
500
what happens to an ice cube when you put it in very hot water. In what direction is energy flowing
when it is placed into the water it rapidly absorbs thermal energy and so the hot water goes into the cold ice cube
500
How have human needs for thermal energy changed over time and give examples of how thermal energy technology has changed to meet those needs
humans don't have to do as much to work stuff back then they had to use tons of energy to make a fire an cook food now we flick a switch and cook food on an oven like they had to hunt back then and now we buy stuff from the grocery store
