Answer:
D
Explanation:
If the pressure remains constant then the temperature and Volume are all that you have to consider.
Givens
T1 = 19oC = 19 + 273 = 292o K
T2 = 60oC = 60 + 273 = 333oK
V1 = 250 mL
V2 = x
Formula
V1/T1 = V2/T2
250/292 = x/333
Solution.
The solves rather neatly. Multiplly both sides by 333
250*333 / 292 = 333 *x / 333
Do the multiplication
250 * 333 / 292 = x
83250 / 292 = x
Divide by 292
x = 285.1 mL
The answer is D
Answer:Total energy gained by 15.71 g is 3090.6471 joules
Explanation:
Given:
Q = heat gained by the 15.71 gram mass of gold
c = specific heat capacity of gold = 0.1291
m = mass of gold =15.71 g
Heat gained by gold = 
=3090.6471 joules
<span>Other than rain what kinds of precipitation are there, the following includes: snow, hail, sleet. Precipitation refers to any things that falls down brought by a natural phenomenon because of a chemical reactions and settles to the bottom of a solution. The higher the degree of the precipitation, the bigger the area has that source.</span>
