Three containers C1, C2 and C3 have water at different temperatures. The table below shows the final temperature T when different amounts of water (given in liters) are taken from each container and mixed (assume no loss of heat during the process) C1 C2 C3 T 1ℓ 2ℓ -- 60°C -- 1ℓ 2ℓ 30°C 2ℓ -- 1ℓ 60° 1ℓ 1ℓ 1ℓ θ The value of θ (in °C to the nearest integer) is

1. 50
2. 50.00
3. 50°C
4. 50°

Correct answer: 50.00

Solution

The correct option is 50.00 because it represents the final temperature θ when equal amounts of water from each container are mixed, and it is expressed in a precise format that aligns with the scientific convention of reporting temperature.
