What are the following options?
Half-life is the time it takes for the radioactive material's mass to decrease by half.
So, half of 96 is 48
half of 48 is 24
half of 24 is 12
half of 12 is 6
96->48->24->12->6
You count how many arrows (->) there is.
Which is 4
Then you use the 12 minutes the question gave you to do:
12 divided by 4
= 3
So, one half-life (Or the time it takes for the radioactive material's mass to decrease in half) is 3 minutes
and every 3 minutes it will decrease by half.
Answer:
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
