If 200 cm^3 of tea at 95 degrees celsius is poured into a 150g glass cup initially at 25 degrees celsius, what will be the common final temperature t of the tea and cup when equilibrium is reached, assuming no heat flows to the surroundings?

The final temperature is 85.86°C.

Explanation:

Given that,

Mass of tea = 200 g

Mass of glass = 150 g

Initial temperature = 25°C

We need to calculate the final temperature

When equilibrium is reached, assuming no heat flows to the surroundings

So,

We know that,

Specific heat of tea = 1.00 cal/gm° C

Specific heat of tea = 0.20 cal/gm° C

Put the value into the formula

Put the value of initial temperature

Hence, The final temperature is 85.86°C.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
