if we mix 2 substance A and B of 30 degrees celsius and 70 degrees celsius respectively.what will be the temp of the mixture

Please help Me

If there are equal amounts of A and B, and if they are the same material, then you reach a mean temperature (50 C) at equilibrium.

In general, you have to know the relative amounts of each substance and the specific heats of each, to be able to predict the final temperature.

To find out the temperature of the mixture when two substances with different temperatures are mixed, we need to consider the concept of heat transfer and thermal equilibrium.

The principle of thermal equilibrium states that when two objects at different temperatures are brought into contact, heat will flow from the hotter object to the colder object until both objects reach the same temperature.

In this case, Substance A is at 30 degrees Celsius, and Substance B is at 70 degrees Celsius. To determine the final temperature of the mixture, we can use the principle of conservation of energy:

(mass of Substance A * specific heat capacity of Substance A * change in temperature of Substance A) + (mass of Substance B * specific heat capacity of Substance B * change in temperature of Substance B) = 0

Since we don't know the specific heat capacities or masses of Substances A and B, we cannot directly calculate the final temperature of the mixture. However, we can make some assumptions to estimate the approximate temperature of the mixture.

If we assume that the masses and specific heat capacities of A and B are equal, the final temperature of the mixture would be the average of the initial temperatures:

(final temperature) = (initial temperature of Substance A + initial temperature of Substance B) / 2
= (30 + 70) / 2
= 100 / 2
= 50 degrees Celsius

So, if the masses and specific heat capacities of Substances A and B are equal, the temperature of the mixture would be approximately 50 degrees Celsius.
