Question

Quizplus · Accepted Answer

To find the final temperature, we can use the formula:
(m1 x T1 + m2 x T2) / (m1 + m2)
where m1 and T1 are the mass and temperature of one substance, and m2 and T2 are the mass and temperature of the other substance.
Plugging in the values, we get:
(50 g x 20°C + 50 g x 40°C) / (50 g + 50 g) = 30°C
Therefore, the final temperature of the mixture is 30°C, which is option C.
