Answer :
Final answer:
The final temperature of the mixture of 1 liter of water at 30 degrees Celsius and 1 liter at 50 degrees Celsius will be the average of the two temperatures, which is 40 degrees Celsius. Option d is correct.
Explanation:
When mixing two quantities of water with different temperatures, the final temperature of the mixture will be an average of the two starting temperatures. This is due to the principle of heat exchange which states that warmer substances will lose heat while colder substances will gain heat until an equilibrium is reached. In this case, 1 liter of water at 50 degrees Celsius will lose heat and 1 liter of water at 30 degrees Celsius will gain heat.
So, the temperature of the mixture will be the average of 30 degrees and 50 degrees, which is 40 degrees Celsius. As such, the correct answer is (d) between 30 degrees Celsius and 50 degrees Celsius.
