Specific heat Definition and 465 Threads

In an experiment, .02 kg of substance is heated in a bath of boiling water until its temperature is apporoximately 100*C. The substance is the placed in an insulated container that is holding .10 kg of water at 25*C. The final equilibrium temperature of the mixture is 32*C. The specific heat of...

Please Help! - Specific Heat Problem... I have been stuck for a while, it's online (Webassign), so it told me my answer was wrong. ------- A 6.3x10^2 g sample of water at 90.0°C is mixed with 4.45x10^2 g of water at 22.0°C. Assume no heat loss to the surroundings. What is the final...

problem: a 1350 kg car is moving at 23m/s. the driver brakes to a stop. the brakes cool off to the temperature of the surrounding air, which is nearly constant at 15 celsius, what is the total entropy change? i know that S=integral of dQ/T since T is constant i can take it out of the...

A problem in my book asks me to compute the mass of a gas molecule given its specific heat at constant volume. ("Take c_v = 0.075 cal/g C° for argon and calculate the mass of an argon atom and the molar mass of argon.") Can I get a hint on where to go with this? I don't see any way of...

I have been trying to understand the concept of specific heat ratios. From what I gather, the ratio is defined as the quotient of the Specific heat at constant pressure and the Specific heat ratio at constant volume. Could anybody give me an insight into what leads to gases having different...

I am currently studying thermochemistry and specific heat capacity has been discussed. From observing a list in order of specific heat from highest to lowest and then comparing to a list of densities, it seems to me that the denser a substance is, the lower the specific heat. Is this true and if...

Problem 7. Given; specific heat of water=4186 J/kg* degrees Celcius Brass is an alloy made from copper and zinc. A 0.66 kg brasss sample at 98.6 degrees Celciusus is dropped into 2.33 kg of water at 4.6 degrees Celcius. If the equilibrium temperature is 7.0 degrees Celciusus, what is the...

Hello, Faizan Here Can anyone show ne how to derive the formula of specific heat capacity pls.? Also i need the derivation of the formula of magnification power of a lens? Thanks in advance to anyone who helps me.

Hey, can anyone describe to me an experiment to find the specific heat capacity of ice? Keep it simple please :smile: Thanks in advance :wink:

c = 0.182772277 cal/g * C What type of substance is it? it's not glass.

specific heat? Hey guys….I need help with another problem. Q: Below are two sets of data from an experiment to determine the specific heat of a metal sample. For which mass will t the uncertainty n the specific heat be greater? Explain your answer. The uncertainty in all temperature...

Hello again! I'm not sure if this is difficult but I believe that everyone have experienced this... I can't explain it... =) Sorry about that. Anyway, here's my problem... At noon, when the sand in the beach is already hot, why does the water still feel cold? Early in the night...

Specific Heat Capacity help! This question is simple but I'm a little confused, it involves beach breezses, temperature, and convection. Sand on the beach get much hotter than water on sunny day so air above sand heats up and rise due to convection then cold air moves in from over water...

Hello, 150kcal of heat raises the temp of 2.0kg of material by 400 degrees F. Whats the materials specific heat capacity? I cam up with 1.35 kcal/kg degrees C. is this correct? Thanks! Dx :wink:

Hello. The other day i couldn't sleep, so i started to think. After some long thinking, i reached a concludion (i was half sleep anyway !). I reached the conclusion that the specific heat of any matter is supposed to raise as the temprature of the body raises. So, am i kind of right ? Thank...
