- 75.0 gram sample of water at 25.0 degrees Celsius is mixed with a 100. gram sample of water at 60.0 degrees Celsius. What is the final temperature of the water? (No units necessary in the answer)

45

Explanation:

= First sample mass of water =

= Change in temperature of the first sample of water =

= First sample mass of water =

= Change in temperature of the first sample of water =

= Final temperature of the mixture

= Specific heat of water

Heat lost by water will be equal to the heat gained so we get

The final temperature of the water is 45.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
