Answer:

Temperature: The rate of evaporation increases with an increase in temperature. Surface area: The rate of evaporation increases with an increase in surface area. Humidity: The amount of water vapour present in the air is called humidity.

may this help you.

hello,

here is your answer:

**********

Factors affecting evaporation:

⇒ Increase in surface area - if the surface area is increased the rate of evaporation increases.

⇒ Increase in temperature - with increase in temperature, more particles get enough kinetic energy to turn into vapour.

⇒ Decrease in Humidity - air around us can't hold more than a definite amount of water vapour, if amount of water vapour is already high, then rate of evaporation decreases.

⇒ Increase in wind speed - with increase in wind speed, the particles of water vapour move away with the wind, decreasing the amount of vapour in the surrounding atmosphere.

**********

hope this helped,

:)

14. A child's lungs can hold 2.20 L. How many grams of air do her lungs hold at a pressure of
Alenkasestr [34]

Answer:

Explanation:

Use the gas equation: PV=nRT

P=pressure

V=Volume

R= gas constant of around 8.31 J/K/mol

T=temperature

n= number of moles

To find n, Rearrange:

n=PV/RT

102kPa= 102,000 kilo pascals which standard form is 102 x 10^3

Convert Celsius to kelvin, which you just add 273.15. So:

37+273.15=310.15 K round to a whole number is 310 K

Sub in all numbers to calculate the mol

n= 102 x 10^3 x 2.20 x 10^3/ 8.31 x 310 (cross out 10^3 as this will make a big number)

n=102 x 2.2/8.31 x 310 =0.087 mol

We know 1 g=29 moles

Multiply 29 moles with 0.087 to find the grams

29*0.087=2.523, which to one d.p is 2.5 g

Hence, the child's lung will hold 2.5 g of air.

Hope this helps you  :)

Have a nice day!!

In which type of condition is a conditions is a landslide most likely to occur
masha68 [24]

Answer:

<u>B. In a wet, hilly area</u>

Explanation:

We know that for a landslide to happen, there has to be a down hill slope so it can fall.

This eliminates answers C, D and E.

So we are left with A and B

Now we can look at this in a real life scenario. If you have ever walking on wet ground, you will know that is weaker than dry ground. Knowing this, we know the answer will have to be answer B.
