Answer:
I don't understand what you are asking
Answer:
8.10 hours.
Explanation:
You start with 500.0g.
After the first half-life, you have 250.0g.
After the second, you have 125.0g.
After the third, you have 62.50g.
Therefore, it takes three half-lives to decay to 62.50g.
Therefore, the elapsed time must be triple the length of one half-life.
24.3
3
=
8.10
, so it is 8.10 hours.

Answer:
Do you need the definition or the equation to find it?
Explanation:
Equation:
Mass=volume x density
Answer:
Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.

here is your anserw please rate me the brainlest
There is a typo in the question. hopefully, i assumed the correct number.
when volume and temperature are given, that means you need Charles' law. remember that with any gas formula, the temperature has to be in Kelvin which can be determined by simply adding 273 to Celsius.
Charles' law---> V1/T1 = V2/T2
V1= 2.8 m3
T1= 20 C = 293 K
V2= 0.2 m3
T2= ????
let's plug in the values
2.8/ 293 = 0.2/ T2
T2= 20.9 Kelvin
to change the answer to Celsius, just subtract 273 to the temperature
20.9 - 273= -252 Celsius
