2. imagine now that one tried to repeat the same measurement, but between the time that the warm water was measured and the time it was mixed with the cooler water, the warmer water has lost 3060 cal to the environment. calculate the final equilibrium temperature assuming no additional heat loss after mixing occurs.

The final temperature is 64.28°C.

Explanation:

Imagine now that one tried to repeat the same measurement, but between the time that the 400 cm³ of warm water was measured at 88°C and the time it was mixed with the 130 cm³ of cooler water at 15°C, the warmer water had lost 3060 cal to the environment. Calculate the final equilibrium temperature assuming no heat loss after mixing occurs.

Let the temperature of hot water before mixing is t

We need to calculate the temperature

Using formula of energy

Put the value into the formula

We need to calculate the final temperature

Using formula of temperature

Put the value into the formula

Hence, The final temperature is 64.28°C.

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^
