Specific Heat Capacity help? I know how to work out how much energy is needed to raise a temperature with the basic formula, but how do I work this out?
A girl has a bottle of water. The bottle has two litres of water in it (2ltr weighs 2kg). The water...

Q = mcdelta(T)
Q = (2 kg)(1000 g/1 kg)(1 cal/g C)(5 C)
Q = 10,000 cal .

H ow do I find out Z factor and ratio of specific heats using HYSYS for relief valve sizing? I have a service comprising of a mixture of iso-butane and normal butane.

Throughout my time doing physics I have noticed that ice has a lower specific heat capacity than water.
I dont understand why.
To me it seems that the bonds between water molecules in a solid are stronger and hence require a greater deal of thermal energy...

the conclusion is that the enregy given to liquid water is used to other things that just "rising" the temperature. .

"Laltazan" has been a great help. And he seems to know what he is talking about. I have 39 years in this field as an Auto Tech. I used to work for VW, and a Jeep dealership. Now I'm just doing side jobs. So I don't have Alldata any longer. So it's nice...

The Forums are a great place to carry on general conversations... .
We all benefit when a problem is discussed on Answers or on the Edmunds forum .
So we don't enable "personal" help via email.
Minute) Emails may get you personal help but not help others .

Heat energy required and heat loss
Hi all,
I am new to this forum. I am actually stuck up with a problem related to heat energy. I have two steel tanks, both are of similar dimensions (1m,1m,2m). One of which is filled with water and the other is filled...

Then look up the heat of fusion for ice and do Q2=m*(Heat of fusion(1) H = (m)(c)(dT)
H = (0)(c)(dT) = 0 J

So I've hear all kinds of reasons why certain drinks use certain shapes of glasses, but I've never seen any evidence other than anecdotal.
I figured I would list the ones I've heard, and you can add to the list, or if you can debunk or support it, that...

Way too much heat for me.
I've seen those brandy snifter holders that hold a glass over a tea-light candle .
It gets while it warms up and the heat from my hand is all it needs.
