Ideally, when a thermometer is used to measure the temperature of an object, the temperature of the object itself should not change. however, if a significant amount of heat flows from the object to the thermometer, the temperature will change. a thermometer has a mass of 33.0 g, a specific heat capacity of c = 804 j/(kg c°), and a temperature of 15.4 °c. it is immersed in 149 g of water, and the final temperature of the water and thermometer is 56.0 °c. what was the temperature of the water in degrees celsius before the insertion of the thermometer?

Answer : The temperature of water is,

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

where,

= specific heat of thermometer =

= specific heat of water =

= mass of thermometer = 33.0 g

= mass of water = 149 g

= final temperature =

= initial temperature of thermometer =

= initial temperature of water = ?

Now put all the given values in the above formula, we get:

Therefore, the temperature of water is,

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
