The amount of heat released when 12.0g of helium gas condense at 2.17 K is; -250 J
The latent heat of vapourization of a substance is the amount of heat required to effect a change of state of the substance from liquid to gaseous state.
However, since we are required to determine heat released when the helium gas condenses.
The heat of condensation per gram is; -21 J/g.
Therefore, for 12grams, the heat of condensation released is; 12 × -21 = -252 J.
Approximately, -250J.

The answer is D. 5^-2 times 5^4.
The missing number is 6. 3.6-.65 = 2.95
3.6 - 2.95 = .65
Hope it helps ;)))
Answer:
D. f(t) = 192,345(1.04)^t
Step-by-step explanation:
<em>I took the test and it was right. </em>
Also that is the original price and when you look at exponential functions, the starting point or original price is always first the then rate of increase. The table just shows how it increased in year 1 and 2.
Hope this helps. :)
Answer:
Mean Is 3 , Median Is 3
Step-by-step explanation:
The mean is the usual average, so I'll add and then divide:
0 + 1 + 2 + 3 + 4 + 5 + 6 = 21 divide by 7 you'll get 3
The median is the middle value, so first you'll have to rewrite the list in numerical order: There are seven numbers in the list, so the middle one will be the answer which is 3
0 , 1 , 2 , 3 , 4 , 5 , 6
