A sample of ethene gas in a syringe is heated from 20 degree to 100 degree celcius. The pressure remains constant. Describe and explain, in terms of the kinetic particle theory, what happens to the volume of the gas.

If the temperature is increased, the average speed and kinetic energy of the gas molecules increase.

According to Charles law, f the temperature of a gas is increased, a constant pressure may be maintained only if the volume occupied by the gas increases. Thus, the volune increases with an increase in temperature.

This will result in greater average distances traveled by the molecules to reach the container walls, as well as increased wall surface area.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
