The amount of time it takes for 1/2 of it to decay or dissapear

this is liike compound interest because it takes the same amount of time to decay 1/2 of it, regardless of the amount

example

lets say half life of element x is 1 year
if yo has 32 grams, after  1 year, it decays to 16g
2 years decays to 8
3 years decays to 4
4 years decays to 2
5 years decays to 1
etc

hope this helps (I'm not the best at chem)

20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
MrRa [10]

Answer:

T2 = 550K

Explanation:

From Charles law;

V1/T1 = V2/T2

Where;

V1 is initial volume

V2 is final volume

T1 is initial temperature

T2 is final temperature

We are given;

V1 = 20 mL

V2 = 55 mL

T1 = 200 K

Thus from V1/T1 = V2/T2, making T2 the subject;

T2 = (V2 × T1)/V1

T2 = (55 × 200)/20

T2 = 550K
