You add 100 mL of water at 20 C to 200 mL of water at 80°C. What is the most likely final temperature of the mixture?

Respuesta :

I believe it would be 60°C

The final temperature is 60°C

What is meant by Temperature?

A measure of the warmth or coldness of an object or substance with reference to some standard value.

What is meant by Specific heat?

  • A measure of the amount of heat needed to increase a substance's temperature by one degree Celsius per gram.
  • Specific heat is usually measured in Joules per gram per degree Celsius (J/g °C)

What is Calorimetry?

Calorimetry is the practice or science of observing changes in a body's state variables in order to compute the heat transfer related to such changes, such as physical changes or phase transitions under particular circumstances.

How to solve the Problem?

Let c be the specific heat of water.

According to the principle of calorimetry.

Heat lost by hot water = heat gained by cold water

200 * c * (80 - T) = 100 * c * (T - 20)

∴ 200c (80-T) = 100c(T-20)

∴2 (80-T) = T - 20

∴160-2T=T-20

∴ 160+20 = T +2T

∴180 = 3T

∴T = 60 C    

Hence the Final temperature is 60°C
