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.
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 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)
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
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.)
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.
You can find the change in temperature by subtracting the initial temperature from the final temperature. For example, if the initial temperature is 20 degrees Celsius and the final temperature is 30 degrees Celsius, the change in temperature would be 10 degrees Celsius (30 - 20 = 10).
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.
In a graph showing temperature change of a material over time, the x-axis typically represents time while the y-axis represents temperature. The slope of the line indicates the rate of temperature change, with a steeper slope representing a faster change in temperature. The point at which the line intersects the x-axis denotes the initial temperature of the material.
It is the temperature at the start of the experiment.
This is the temperature at which an experiment begins.
Changing the initial temperature of the copper will affect the amount of heat energy it has because temperature is directly related to the kinetic energy of the particles in the copper. A higher initial temperature means the particles have more kinetic energy and therefore more heat energy. Conversely, a lower initial temperature means less heat energy present in the copper.
The initial boiling point is the temperature whereby the first drop of distillate has appeared.
To calculate the delta temperature, you will take the difference between the final and initial temperature.
That would depend on many factors, such as the material the container is made of, the color of the container, how much water is in the container, and the starting temperature of the water. You really need to measure the temperature after six hours with a thermometer.

No, it is a metal that has to be smelted out of a mineral called wolframite. It is this wolframite that is the initial raw material.
