A gas in a large syringe has a volume of 300ml at 45°C. The temperature is lowered to 30°C. What is the new volume of the gas in the syringe? (N and p are constant). Hint:Convert temperature to kelvin before calculating (°C+273=K)

V1=300ml

V2= x ml

T1= 45 Celsius

T2= 30 celcius

Do the math

you will get

318x=90900

divide by 318

x=285.8 ml (rounded)

Explanation:

you have to add 45 and 30 (separately because the temp. has to be in kelvin) to 273... so V2 equals 2858.8 ml

Fist a cloud of dust and gas formed, then the nuclear fusion takes place. Then the nebula shrinks and spins. The last step is when the nebula flattens into a disk.

Or

1. The cloud of dust and gas formed
2.The nuclear fusion takes place
3.The nebula shrinks and spins.
4.The temperature increases
5.The nebula flattens into a disk.
