Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
Explanation:
Answer:
A
Explanation:
The high humidity, in conjunction with warm temperatures, creates massive amounts of warm, moist air rising into the atmosphere, where it can easily form a thunderstorm. As the process of evaporation and condensation occurs, these droplets collide with other moisture that is condensing as it rises.
360.18 K is the Kelvin temperature to which 10.0 L of a gas at 27 °C would have to be heated to change the volume to 12.0 L.
Explanation:
Data given:
Initial volume of the gas, V1 = 10 litres
Initial temperature of the gas, T1 = 27° C or 273.15+27 = 300.15 K
Final volume of the gas obtained, V2 = 12 Litres
final temperature to obtain the above volume, T2 =?
temperature value in Kelvin
Applying Charles' Law to the data given,
rearranging the equation to get T2,
T2 =
Putting the values in the equation:
T2 =
T2 = 360.18 K
The gas will be heated at the temperature of 360.18 K to get its volume changed to 12 litres.
1.7 Btu
1 watt = 3.41214 Btu/h
1watt * 1h = 3.41214 Btu/h * h
1 = 3.41214 Btu/ (watt*h)/
0.5 watt * h = 0.5 watt*h * 3.41214 Btu/(watt*h) = 1.706 Btu
