To calculate the heat absorbed by a person's hand when 100 grams of water at 100°C cools to 37°C, the focus shifts to the energy released during this temperature change. The specific heat capacity of water is essential for determining the total energy transfer. The discussion emphasizes that the energy released from 1 gram of water changing by 1°C is a crucial factor in solving the problem. Understanding this concept is key to calculating the overall heat absorption by the hand. The conversation highlights the importance of thermal energy transfer in this scenario.

Homework Statement



How much heat is absorbed by a person’s hand if 100 grams of liquid water at 100°C is poured on his hand? (Assume the final temperature of the water will be normal body temperature of 37°C)


Homework Equations


dont have any


The Attempt at a Solution


dont have one.

The water changes temperature. So maybe a better question to ask is how much energy is released by 100 g of water when it changes from 100o to 37o C? :wink:
 
i just copied and pasted this question from my homework. i didnt word it

Okay. :cool:

Then how much energy is released from 1 gram of water when it changes 1o C?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
