An ideal gas cannot be
a. heated
b. condensed
c. compressed
d. cooled

C compressed

Explanation:

An ideal gas cannot be compressed.

The compressibilty of a gas depends on the density of that gas.

Ideal gases have constant density and the densities are very low that the gas molecules don't interact much.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
