Why the level of mercury should change at all when the bulb of the thermometer is brought in contact with another object?
The level of mercury changes in a thermometer when it comes in contact with another object because the temperature of the object affects the temperature of the mercury. Heat transfers between the object and the mercury, causing the mercury to expand or contract, which in turn changes its level in the thermometer.
What is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
What doesnot cause the height of mercury column to vary?
A change in the material of the container holding the mercury does not cause the height of the mercury column to vary. The height of the mercury column is determined by the atmospheric pressure acting on the surface of the mercury in the container.
What Force That Causes A Change In The Motion Of An Object Is Called?
The force that causes a change in the motion of an object is called an external force. This force can come from various sources, such as gravity, friction, or contact with another object.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).

Why reactants cannot be brought back after chemical change?
because chemicals were already used and diverted into another chemicals
Is mercury being heated to produce mercury vapor a physical change?
Yes, heating mercury to produce mercury vapor is a physical change because no new substances are formed. The change is reversible, and the mercury can return to its original state once cooled back down.
What is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.

Describe an incident that has brought about a significant change?

Is oxidizing mercury a physical or chemical change?
Oxidizing mercury is a chemical change because it involves a rearrangement of atoms in the mercury molecules to form new compounds (such as mercury oxide). This results in a change in the chemical composition of the substance.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
