Answer:

Therefore, after the five-minute period, the temperature of the water would be approximately 41.98°C.

Step-by-step explanation:

To determine the final temperature of the water, we can use the equation:

Q = mcΔT

Where:

Q is the heat lost (in joules)

m is the mass of water (in grams)

c is the specific heat capacity of water (approximately 4.18 J/g°C)

ΔT is the change in temperature (in °C)

In this case, the mass of water is 1000 g, the initial temperature is 50°C, and the heat lost is 33,600 J. We need to find the change in temperature, ΔT.

Rearranging the equation, we have:

ΔT = Q / (mc)

Plugging in the values:

ΔT = 33,600 J / (1000 g * 4.18 J/g°C)

= 8.02°C

Therefore, the change in temperature is 8.02°C.

To find the final temperature, we subtract the change in temperature from the initial temperature:

Final temperature = Initial temperature - ΔT

= 50°C - 8.02°C

= 41.98°C

Therefore, after the five-minute period, the temperature of the water would be approximately 41.98°C.
