How does a sample of water at 38 celsius compared to a sample of water at 295 k?

Explanation:

In order to compare both samples we must express them to the same temperature units:

Conversion of 295k to degree celcius:

     T°C = 295 - 273 = 22°C

Now, we can easily compare both waters now:

The water at 38 degree celcius would be warmer compared to that which is at 22 degrees celcius. The molecules at 38 degree celcius would be able to move more freely.

The water at 38 °C has faster-moving molecules than the sample at 295 K.

Explanation:

i took the quiz

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
