If I have 31 liters of helium in a balloon at 9°C and increase the temperature of the balloon to 28°C, what will the new volume
Ede4ka [16]

Answer: The new volume of the balloon is 33 liters while T2 is 301K

Explanation:

Initial volume of helium V1 = 31 liters

Initial temperature T1 = 9°C

Convert temperature in Celsius to Kelvin

( 9°C + 273°C = 280K)

Final temperature T2 = 28°C

( 28°C + 273°C = 301K)

Final volume V2 = ?

According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.

Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2

31/280 = V2/301

To get the value of V2, cross multiply

V2 = (31 x 301) / 280

V2 = 9331 / 280

V2 = 33.325 liters (approximated to 33liters)

Thus, the new volume of the balloon is 33 liters while T2 is 301K

Please help me !!!!
just olya [345]

Answer:

12, 28, 16

Explanation:

If we are trying to find mass, neutrons are our guy. 28 "mass points" means 28 neutrons. Each neutron is one point

We know there are 12 protons and electrons if we look at a table of elements, the number in the top-left is always the number of protons and we can subtract mass from the protons to get our electrons
