You would ALSO have to assume that the materials have the same shape.The material that cools down fastest would be the one that has the least specific heat capacity.

What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
A paraffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn The can contained 250.0 of water at an initial temperature of 13.0 C?
A paffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn. The can contained 250.0 of water at an initial temperature of 13.0 C. What is the heat of combustion in kJ/g of paraffin? The specific heat capacity of water is 4.184 J/(g C)
A 10.0L balloon is filled with He gas at a pressure of 655mm Hg What is it's new pressure assuming no change in temperature if the volume of He is changed to 1.5L?
You can use the Ideal Gas law which says that for an ideal gas the pressure times the volume divided by the temperature must be a constant number. And in this case since you are given that the temperature is a constant number then the gas law becomes "the pressue times the volume is a constant number". This means whatever their product is at one time , it will equal their product at a different time. The equation would be: Pf x Vf = Pi x Vi where the i & f mean initial & final. You solve this for the unknown final pressure ,Pf as: Pf = ( Pi x Vi )/Vf = ( 655 x 10 )/1.5 = 4367 mm of Hg
An ordinary glass is filled to the brim with 350 mL of water at 100 C If the temperature decreased to 20C how much water could be added to the glass?
Difference in volume = (initial volume) (coefficient of volume expansion of water) (difference in temperature) coefficient of volume expansion of water=0.0002ml/degree celsius (not sure about the value. Better get help from a teacher.)
A total of 500 kj of heat is added to 1 kg of water at 20 degrees Celsius what is the temperature?
Q = MC(Tf - Ti) Q is the heat added; M is the mass of the water; C is the heat capacity of water (look it up); Tf is the final temperature (this is what you solve for); Ti is the initial temperature of the water. Make sure your units all jive. For example C would have to be in units of kj/kg-deg for you to get the correct answer ,using the units given.
What soda dissolves chalk fastest?
None. It will depend on the initial temperature of the soda, not the brand.
Which evaporates the fastest tap water or fresh water?
This depends only on the initial temperature and the presence of some significant impurities.
If i have the initial and after temperature how would i be able to find the change in temperature?
You subtract the initial from the after, and the result is the change. If the initial temperature is 50º and the after is 70º, then the change is +20º.
What is meant by initial temperature rise of IC?
A: As power is turn on the temperature of the IC is at ambient temperature or the initial temperature then becomes the increase in temperature due to heating.
What is initial temperature?
This is the temperature at which an experiment begins.
What is initial temperature mean?
It is the temperature at the start of the experiment.
When nitrogen stored at 6000 psi is released into the atmosphere what is it's temperature?
The final temperature will depend not only on the initial and final pressures, but also on the initial temperature and whether the expansion is adiabatic.
Which of the following reaction mixtures would you expect to have the fastest initial rate?
middle 1
What is initial point?
The initial boiling point is the temperature whereby the first drop of distillate has appeared.
How to calculate delta temperature?
To calculate the delta temperature, you will take the difference between the final and initial temperature.
What is the initial temperature of ammonium chloride in water?
68384838
What is Initial boiling point?
The initial boiling point is the temperature whereby the first drop of distillate has appeared.
