IT measures it by the alcohol or Mercury being touch by heat so the fluid rises.There is a chemical in the thermometer (the red liquid ) and it reacts to heat or coldness. cold makes it retract and the heat makes it expand

That is NOT a deformation thermometer but an expansion thermometer. A deformation thermometer has a bimetallic strip. This is a strip made by joining together two strips of metal with very different coefficients of thermal expansion. When heated, one of the metals expands much more than the other. But, because they are bonded together it is not permitted to expand freely and as a result the bimetallic strip is deformed. The amount of deformation is converted to a temperature scale for display.

Explain why it is necessary to have a standard thermometer?
to make the same type of measurement around world so that there is a universal when measuring certain substances.
Explain the used of a maximum minimum thermometer is used?
i dont no just leave me alone
Does speedometers of a car measures its velocity full explain?
No. Velocity consists of a magnitude and a direction. The magnitude of velocity is called "speed", and that's what the speedometer measures. But it displays no information concerning the direction in which the car is moving.
Explain why a bimetallic strip is used in a rotary thermometer instead of a strip with only one kind of metal.?
A bimetallic strip is made from two different metals that expand at a different rates. Two strips of these metals are bonded together, and when the temperature changes, one side expands more than the other, forcing the bimetallic strip to curl (the longer side would be on the outside of the curl). So if one end is clamped, the other moves. This motion is used to turn the dial of the thermometer.
Does two objects at different temperature have same thermal energy explain?
No,two objects at different temperature does not have the same thermal energy because both objects have different temperature .object with high temperature has more thermal energy and the object with low temperature has less thermal energy.
Explain how a barometer and a thermometer are not alike?
One measures temp other barometric press
What does a compound pressure gauge measure?

Explain how to take the internal temperature of meat and why is this is important?
Stick a meat thermometer in the centre of the meat. Temperature is an indication of how well the meat is cooked - i.e rare, medium rare, well done...

Explain how a barometer and a thermometer are alike?
A thermometer and a barometer are alike, because a thermometer tells temperature, and a barometer tells air pressure. They sort off connect, because when you have lower air pressure, you get colder temperatures and when you have higher air pressure, you know then that the temperature will be hotter. You can kinda tell by looking at only one piece of data, what the other piece might be. I'm pretty sure that's right, I'm only in 7th grade.
Explain how a liquid thermometer measures temperature?
OK basically depending on what thermometer. the glass tube is filled with either alcohol or Mercury. and when it gets hotter, the liquid expands and takes up more space inside the tube. and colder.......the liquid compacts and moves down the tube.....and it's taken years to calabrate the markings on the tube to show the correct reading.
Explain how you would use a wet bulb thermometer and a dry bulb thermometer to find the relative humidity?
the wet bulb is cooler
Explain how an ordinary glass fever thermometer is designed?
By using glass.
what are the internal and external controlling factors for deformation of rocks (explain how)?
Internal Controlling Factors: Strength: The strength of the rock determines the amount of deformation that can occur before it fractures. Different types of rocks have different strengths, so the amount of deformation that can occur will vary depending on the type of rock. 2. Temperature: The temperature of the rock determines the amount of deformation that can occur. When rocks are heated, they become more ductile and can deform more easily than when they are cold. 3. Composition: The chemical composition of the rock can also influence its ability to deform. Rocks with higher amounts of silica tend to deform more easily than rocks with lower amounts. External Controlling Factors: Pressure: The external pressure applied to the rock can influence the amount of deformation it can endure. Higher pressures tend to cause rocks to deform more easily than lower pressures. 2. Stress: The type of stress applied to the rock can also influence how much deformation it can endure. Different types of stresses can cause different amounts of deformation. 3. Time: The amount of time over which the deformation takes place can also influence the amount of deformation that can occur. Deformation can occur over
