Can molecules break apart into atoms during a chemical change?

No, being that atoms are only divisible under special spectrometry conditions in a laboratory.


What increase the rate of transpiration in a plant?

The rate of transpiration depends on some environmental factors such asTemperature and windWhen the temperature is high rate of evaporation increases as warm air can hold more water vapours than the cold air. Windy condition also increase the rate of transpiration as wind remove water vapours from around the leaf. HumidityWhen there is more humidity in air, transpiration would be considerably low as the air is already saturated with water vapours and it will be unable to absorb more water so little water will diffuse out of the leaves. LightLight greatly influences the opening and closing of stomata. During day light the stomata remain open and allow water vapours from the leaves to diffuse into the atmosphere. Atmospheric pressureReduction in the atmospheric pressure enhances the rate of transpiration.

Pressure in the aorta is greatest during what?

The pressure in the aorta is greatest during ventricular systole, which is when the heart contracts and pumps blood into the aorta. This creates a surge in pressure that is known as systolic blood pressure.


Can any one tell me the instruments that will detect air pollutants (gases and vapours released during polymerisation in dental hospital that cause cancer?

Yes. You can find it at Walmart, Target, etc.


Identify the phase of the cardiac cycle to each of the following systolic pressure and diastolic pressure?

Systolic Pressure occurs during ventricular ejection.Diastolic Pressure occurs during ventricular relaxation.


What type of pressure do humans breathe with?

Humans breathe with atmospheric pressure, which is the pressure exerted by the weight of the Earth's atmosphere. This pressure allows air to flow into our lungs during inhalation and out during exhalation.


Can systolic blood pressure equal blood pressure diaslotic?

This is impossible. Systolic pressure is the pressure in the artery during the heart contractions. Diastolic pressure is during heart relaxation. Picture this, and you'd see that it's impossible to have diastolic pressure equal or greater than systolic pressure.


How does intrapleural pressure change during quiet breath?

During quiet breathing, the intrapleural pressure decreases during inspiration as the diaphragm contracts and the thoracic cavity expands, leading to a decrease in pressure inside the lungs. During expiration, intrapleural pressure increases as the diaphragm relaxes and the thoracic cavity decreases in volume, causing an increase in pressure inside the lungs.


Why sericulture is not ecofriendly?

Sericulture is not ecofriendly because during sericulture silkworm is boiled to get silk fibres. Vapours emitted from the boiling cocoon release toxic fumes that pollute the environment.

Can you pop your ears to relieve pressure during a flight"?

Yes, you can pop your ears to relieve pressure during a flight by swallowing, yawning, or chewing gum. This helps equalize the pressure in your ears with the pressure in the airplane cabin.
