Aman heats a balloon in the oven. if the balloon initially has a volume of 0.8 liters and a temperature of 12°c, what will the volume of the balloon be after he heats it to a temperature of 300°c?

1.044 L

Explanation:

Data Given

initial volume V1 of gas in balloon = 0.8 L

initial Temperature T1 of gas in balloon = 12 °C

convert Temperature to Kelvin

T1 = °C +273

T1 = 12°C + 273 = 285 K

final Temperature T2 of gas in balloon = 100°C

convert Temperature to Kelvin

T1 = °C +273

T1 = 100°C + 273 = 373 K

final volume V2 of gas in balloon = ?

Solution:

This problem will be solved by using Charles' law equation at constant pressure.

The formula used

                    V1 / T1 = V2 / T2

As we have to find out volume, so rearrange the above equation

                    V2 = ( V1 / T1 ) x T2

Put value from the data given

                  V2 =  (0.8 L / 285 K) x 373 K

                   V2 = (0.0028 L/K) x 373 K

                   V2 = 1.044 L

So the final volume of gas in balloon= 1.044 L

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
