Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
What is the silver liquid inside of a thermometer called?
Mercury
When you add 5ml of sugar to 250ml of coffee the volume is still 250ml?
When sugar is dissolved in coffee, the sugar molecules is fitted inside the empty spaces in the water molecules. This means that the volume of coffee does not increase.
What happens to the same molecules of water when they cool off?
'They die.".....No.They slow down in movement. When the molecules completely stop, it is called absolute zero. When the molecules slow down it goes from a gas, to a liquid, to a solid.it is impossible to get t o absolute zero .scientists have come with in 1/1000 of a degree but it is physically impossible to get atoms to be completely separated from any natural heat source.
Why do you like Mercury?
i like mercury because it is inside a thermometer
Why does an increase in the number of molecules increase the pressure?
The great the density the higher the air pessure.
If you were able to increase the kinetic energy of the molecules inside your body your body temperature would?
increase
Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.
What is the liquid in the ball of the thermometer?
the liguid inside the thermometer is Mercury.

Why does a thermometer have alcohol inside it?
it does not stick the wall of thermometer it expand regularly
Is there air inside a laboratory thermometer?
no
How does a can crush when you heat up the air inside then let it cool?
You must mean a can that you can heat when open and seal air tight when you let it cool. When you heat it the air inside is heated and expands; so the molecules spread out (less molecules=less air). When the can is sealed and cooled, the molecules move together and that creates a vacuum relative to the outside air pressure, and that pressure crushes the can.
Is there inert gas inside a thermometer?
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.
Why does pumping a soccer ball with an air pump increase the pressure inside the ball?
Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
Ho does a thermometer measure temperature?
A thermometer measures temperature by using the liquid inside of the thermometer. It measures temperature by Celsius and Fahrenheit.
What is a baby incubators receptor?
