Oxygen gas is at a temperature of 40 Celsius when it occupies a volume of 2.3 L. To what temperature should it be raised to occu
Scrat [10]

Answer:

The temperature should be 885K.

Explanation:

In this case we use Charles's Law according to which the volume and temperature of a certain amount of gas are related, keeping the pressure constant. We convert the unit of temperature from Celsius to Kelvin: 0 = 273K -> 40 ° C = 40 + 273 = 313K

V1 / T1 = V2 / T2

2,3L/313K= 6,5L/T2

T2=6,5L/(2,3L/313K)=884, 56K

Do all comets have tails? Explain
Bad White [126]

Answer:

Some (most) has two tails.You can see the tails when the comets go near the sun.There are two types of comet tails,dust and gas ion. Comet tails can be over 600,000 miles (1 million km) long.Because the comet dust particles are so small, they are pushed away from the Sun into a long tail.They are made of ices, such as water, carbon dioxide, ammonia and methane, mixed with dust.There are so much more to discover about comets (which I might not know).

Hope that was helpful.Thank you!!!
