Why must you read the temperature without removing the thermometer from the solution?
The thermometer reading will change from reading the solution temperature.
Why is mercury is preferred in ordinary thermometers?
To measure the temperature calibrated in the thermometer. Mercury as a liquid reacts well to temperature changes. It expands as it gets warmer, so thermometers measure the rise of the mercury to measure temperature.
Why is Mercury in a thermometer?
So that the meter goes up and down due to the fact that mercury is very temp. sensitive and will change density very easily(size)
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Is there a material that will change color when a part of it comes in contact with a liquid And when it loses contact with the liquid it changes back to the original color?
I dont knao of an liquid sensig material but perhaps one of the temperature sensitive materials would do if the liquid you are sensing does not have the same temperature as the substrate on which you coul apply the liquid crystals that change color according to temperature (there are many in a wide array of temperature sensitive ranges)
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
A liquid in glass thermometer is sensitive to small changes in temperature due to the thermal expansion of the liquid contained inside the glass tube. As the temperature increases, the liquid expands, causing it to rise up the calibrated scale of the thermometer. Conversely, as the temperature decreases, the liquid contracts, causing it to subside on the scale. This expansion and contraction of the liquid is highly responsive to even slight temperature variations, making it sensitive to small changes in temperature.
Why must you read the temperature without removing the thermometer from the solution?
The thermometer reading will change from reading the solution temperature.
How do you make thermometers sensitive?
You may increase the heat transfer rate to make it more sensitive to environment such as introducing air flow through thermometer in case of measuring air temperature. It can also design thermometer to be more sensitve with better heat sensitive material and thinner insulation wall. Introducing medium into contact surface (such as oil or water in thermowell) would speed up heat trasfer and make it more sensitive to temperature change.
How do you change a baby thermometer?
a towel will ,change your baby's temperature to cold
What is the function of the a thermometer?
Thermometer is a device that measures temperature or temperature gradient using a variety of different principles.A thermometer has two important elements: the temperature sensor in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value.
Why is mercury is preferred in ordinary thermometers?
To measure the temperature calibrated in the thermometer. Mercury as a liquid reacts well to temperature changes. It expands as it gets warmer, so thermometers measure the rise of the mercury to measure temperature.
What is the function of a laboratory thermometer?
Thermometer is a device that measures temperature or temperature gradient using a variety of different principles.A thermometer has two important elements: the temperature sensor in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value.
Would the temperature change on a thermometer if you hold it by the thermometer bulb?
Yes as your fingers are warmer than the air surrounding the thermometer bulb.
Is there any thermometer which changes its colour due to temperature change?
Yes,its called as "liquid crystal thermometer".
What is the sensitivity of an instrument?
The sensitivity of an instrument is the smallest amount it can measure, of whatever it's built to measure.Anything smaller than the sensitivity of the instrument, and the instrument doesn't even notice it.For example, a laboratory scale can measure the weight of a hair, but a truck scale can't. We say that thelaboratory scale's sensitivity is much smaller (or lower) than the truck scale's sensitivity.
What is the change in temperature when the thermometer reading moves from -10 to 15?
It is a change of 25 units.
How does Mercury within a thermometer change?
The temperature in a Mercury-based thermometer is read by the level of Mercury found in the thermometer. As Mercury heats up, it expands, therefore raising the level of the Mercury of which we see as a higher temperature. On the other end, as the temperature falls, the Mercury contracts and reads at a lower temperature.
