When the glass of a burette expands due to an increase temperature does the diameter of the bore increase or decrease?

When the glass of a burette expands due to an increase in temperature, the diameter of the bore decreases. This occurs because the glass expands uniformly in all directions, including the walls of the bore, which leads to a net reduction in the internal diameter. Consequently, the volume of liquid that can be held in the burette may be affected.


When air expands its pressure and temperature?

When air expands, its pressure decreases while its temperature decreases simultaneously. This is due to the decrease in density as the air molecules move further apart, resulting in lower pressure. The decrease in pressure causes the air to do work on its surroundings, leading to a drop in temperature through the expansion cooling effect.


What are the three physical properties that vary with temperature?

Three physical properties that vary with temperature are volume, density, and thermal expansion coefficient. As temperature increases, volume generally expands, which can lead to a decrease in density. The thermal expansion coefficient quantifies how much a material expands or contracts with changes in temperature.


What is an anterior and posterior diameter ratio for the lungs with breathing?

The anterior-posterior diameter ratio of the lungs with breathing is typically 1:2. During inspiration, the chest expands leading to an increase in the anterior-posterior diameter of the lungs. This ratio can vary depending on factors like lung volume and individual anatomy.


How much does an iron casting expand when heated?

Iron casting typically expands about 0.000012 inches per inch of length for each degree Fahrenheit increase in temperature. The exact amount of expansion can vary depending on the iron alloy used and the specific temperature increase.

Why a gas cools when it expands at high pressure?

When a gas expands at high pressure, it does work on its surroundings to overcome the external pressure. This work done by the gas results in a decrease in its internal energy, leading to a decrease in temperature as per the first law of thermodynamics. So, the gas cools down as it expands at high pressure.


When the air rises does it increase or decrease?

When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.


What happens when air expands?

When air expands, its molecules move farther apart from each other, which leads to a decrease in air pressure and temperature. This process is known as adiabatic expansion, and it occurs due to the increase in volume occupied by the air molecules.


What happens to a gas when it expands?

The behaviour of gas particles are completely different because they randomly move within provided space. For them to expand, we can increase the pressure or either increase the temperature slightly.


How does the expansion of a monatomic gas affect its properties?

When a monatomic gas expands, its properties change. The expansion leads to an increase in volume, which in turn decreases the pressure and temperature of the gas. This causes the gas to cool down and its density to decrease. Overall, the expansion of a monatomic gas results in a decrease in pressure, temperature, and density.


When air expands its pressure and temperature?

When air expands, its pressure decreases while its temperature decreases simultaneously. This is due to the decrease in density as the air molecules move further apart, resulting in lower pressure. The decrease in pressure causes the air to do work on its surroundings, leading to a drop in temperature through the expansion cooling effect.


Does nitrogen expand and contract with temperature?

Yes, nitrogen gas expands with an increase in temperature and contracts with a decrease in temperature. This behavior is consistent with the ideal gas law, which describes the relationship between pressure, volume, temperature, and quantity of gas.


What will happen to pressure when gas expands and volume increases?

When a gas expands and its volume increases, the pressure of the gas will decrease. This is because pressure and volume are inversely proportional according to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature.


What happens if you put a balloon in the microwave?

It would increase in volume. According to Charles' Law, as you increase temperature the volume will increase as well. So if you would put it in a freezer, it would shrink because as you decrease temperature, you decrease volume.


Does plasma expand when heated?

Yes, plasma expands when heated because the increase in temperature causes the particles in the plasma to gain more kinetic energy and move faster, leading to an increase in volume. This expansion results in a decrease in density and an increase in pressure within the plasma.


How does the temperature of gas change when it is compressed when it expands?

Gas is a loosely bound group of molecules that have changed phase from solid to liquid to gas through an increase in thermal energy. Once it has reached the gas phase, heating gas can increase its temperature because the energy will not go into the potential energy of a phase change, but instead the kinetic energy of phase change.


What are the three physical properties that vary with temperature?

Three physical properties that vary with temperature are volume, density, and thermal expansion coefficient. As temperature increases, volume generally expands, which can lead to a decrease in density. The thermal expansion coefficient quantifies how much a material expands or contracts with changes in temperature.
