What is temperature of heating element how to measure it if we know applied voltage or current. Is the temperature said to be even?
When talking of heating elements in the electrical trade the unit of watts is used. The higher the wattage value of the device the higher its temperature output. Heating cables are measured in watts per foot as a way of measuring their heat output. The equation to find wattage of a device is to multiply the voltage of the device times the amperage of the device as stated on the device's nameplate or tag. In most cases the temperature is linear throughout the length of the heating element. The actual temperature can be tested by using a laser spot temperature test instrument.
What is partial condensation in distillation process?
This is the simplest vapour-liquid separation device for gaseous mixtures. It can only be used when the boiling points of the substances are so different that essentially only one of them will condense into a liquid under suitable conditions.

What is a liquid metal that expands and contracts as the temperature changes and is the metal used in thermometers called?
It is dew or ozone
Where are the freezing points and melting points of substances?
They are the same thing. Most commonly the term melting point is used to describe the temperature at which a substance first co-exists in both a liquid and solid state. Freezing point is used usually to describe a substance that is usually liquid at room temperature, such as water. Conversely the term 'boiling point' refers to the first temperature at which the substance exists in both liquid and gaseous states.
How can Mercury be used as a liquid in a thermometer?
it is used in liquid form as in room temperature the mercury is in liquid
Describe how a thermometer uses the thermal expansion of a material to measure temperature?
A thermometer is a device that is used to gauge temperature. Mercury style thermometers used the elemental liquid in a tube of measured diameter and height. The higher the temperature, the higher the observed mercury level is. Thus, the height of the mercury uses marking to indicate which air temperature corresponds to the given height of its liquid expansion.
What characteristics must a liquid have before it can be used in a thermometer?
One thermometric property that is required is that it must vary linearly with temperature. In liquid-in-glass thermometers, the length of the liquid thread is often used to determine temperature. Thus when temperature increases, the liquid must expand uniformly with temperature, so that it can be used to measure temperature accurately.
What device is used for finding the volume of liquid?
beaker
What is a device used to show the temperature?
Thermometer
What is the thermometer used for?
a thermometer is a device that is used to measure temperature.
What is the difference between a thermometer and a thermograph?
A thermometer is a device used to measure temperature at a specific point in time, typically by using a liquid or digital display. A thermograph, on the other hand, is a device that continuously records and graphs temperature over a period of time, providing a visual representation of temperature fluctuations.
How a thermometer is used?
A thermometer is used to measure air temperature, or the temperature within a solid or liquid.
What is the name of the liquid used to reduce friction in engines?
OIL == ==
What substance could be used to cool down a road to reduce the temperature?
The substance that could be used to cool down a road to reduce its temperature is light-colored bitumen.

What device is used for control the body temperature?
The thermometer.
