Answer:
of liquid sodium is required.
Explanation: To calculate the mass of liquid sodium, we use the formula:

where,
q = heat required,
(Conversion factor: 1MJ = 1000000J)
m = Mass of liquid sodium, 
M = Molar mass of liquid sodium, 
c = Specific heat capacity, 
= change in temperature,
(Conversion factor: 0°C = 273K)
Putting values in above equation, we get:


B. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
In an open system, energy transfer would occur between the copper bars and the surroundings.
There are three types of systems:
- Isolated system in which matter and energy is not exchange with the surrounding.
- Closed system there is no exchange of matter but energy is exchanged with the surrounding.
- Open system: there is exchange of both matter and energy.
If the copper bars were placed in an open system matter and energy will be exchanged with the surrounding.

If C3H8O is dissolved in water, it would be expected to be a strong electrolyte.
<h3>
What is a strong electrolyte?</h3>
A strong electrolyte is a solute or solution (already an electrolyte) that can completely dissociates in solution.
C3H8O is one of those compounds expected to be a strong electrolyte.
Thus, if C3H8O is dissolved in water, it would be expected to be a strong electrolyte.

Hello, Brainly User!
As the planet gets warmer, sea level rises for two reasons. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the melt water flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea.
Hope this helps, i was super glad and exited to help you out with this question! Have a great day..
