Answer:
Whenever you are doing calculations with gases and temperature, you must convert the temperature from C into Kelvin. Then, just plug in your values and do the calculation. So, for the first one,
32C + 273 = 305 K
63C + 273 = 336 K
Then, P1/T1 = P2/T2
575 torr / 305 K = P2 / 336 K
P2 = 633 torr
For the second one:
P1/T1 = P2/T2
575/305 = 5750 / T2
T2 = 3050 K

Answer:
1280J are required.
Explanation:
Heat of fusion is defined as the amount of heat required to change its state from liquid to solid at its melting point at constant pressure.
As heat of fusion of gold is 64J/g, there are required 64J to melt 1g of gold at its melting point. The energy required to melt 20g is:
20g * (64J/g) =
1280J are required
Answer: electrolytes hydrate you and give you energy.
Explanation: please add more information to this question. I can tell you this though from my answer it should help you define what is and isn't an electrolyte. I hope that this is helpful to you.
