The thermometer reading will change from reading the solution temperature.
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.
Liquid crystal thermometers utilize liquid crystals that change color based on temperature. Simply place the thermometer strip on the object you wish to measure the temperature of, and the liquid crystals will change color to indicate the temperature. Consult the packaging for a color guide to interpret the temperature reading accurately.
Physical. The mercury doesn't change.
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
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.
The thermometer reading will change from reading the solution temperature.
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.

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.

Yes as your fingers are warmer than the air surrounding the thermometer bulb.
Yes,its called as "liquid crystal thermometer".
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.
It is a change of 25 units.
As the temperature increases, the mercury in the thermometer expands, causing it to rise in the tube. This expansion is due to the heat causing the molecules in the mercury to move faster and take up more space. Conversely, when the temperature decreases, the mercury contracts, causing it to lower in the tube.
