Answer:
<u>The pressure inside becomes : 202.646 KPa</u>
Explanation:
Given ,
- <em>The temperature inside the cylinder is constant</em>
- <em>The number of moles of the gas inside the cylinder will also be constant because it's a closed one.</em>
<em>Now according Boyle's law , </em>
- <em>The pressure of a gas of fixed mass is inversely proportional to its volume at a constant temperature.</em>
Thus ,
- is the initial pressure
- is what we need to find
- - initial volume
- - final volume
∴
The pressure inside becomes : 202.646 KPa
Answer:
Scopolamine.
Explanation:
Scopolamine is also known as hyoscine. It is an anticholinergic, oral topical drug which is used to manage, and prevent motion sickness, and acute treatment. It is must be taken to be effective before the onset of motion sickness.
The scopolamine is helps to prevent communication between the vomiting center which is present in the brain, and the nerve of the vestibule by blocking the action of acetylcholine (it is a chemical which nervous used to transmit massage to each other).
Answer: Physical changes are related to physical properties since some measurements require that changes be made. Melting Point: As solid matter is heated it eventually melts or changes into a liquid state at the melting point. Ice (a solid form of water) melts at 0 oC and changes to the liquid state.
