Ultraviolet light. It can cause skin cancer and that is why we wear sunscreen. We also wear sunglasses because some research has shown that it can damage eyes. Although it can be dangerous, it can also kill certain bacterias.
Answer:
new volume = 30.513L
Explanation:
V1 =17L , P1= 2.3atm , T1=299K , T2=350K , P2 =1.5atm, V2=?
To find the new volume of the gas we will use the combined gas law.
The combined gas law combines Boyle's law, Charles law and Gay-Lussac's law. Its states that the ratio of the product of pressure and volume to temperature is equal to a constant. its expressed mathematically below.
V2 =30.513L
A) they have no effect on air temperature over land on the coast is False
Explanation:
- warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
- the temperature over the land increases when warm ocean currents heat the air above the ocean.
- the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
- so, ocean currents play a major role in regulating the air temperature over land on the coastal region.
