A calorimeter contains 0.750 kilogram of liquid water at 17.0 degrees C. A 0.0580 kilogram block of copper at 98.0 degrees C is placed in the water. What is the final temperature of the system?

You need to know the specific heat for copper. Then use q = mc∆T for copper and water. Heat lost by the copper MUST equal heat gained by the water. You can then solve for T2 of the water.

What is the temperature at 25000 feet with a ground temperature of 62 degrees and a temperature drop of 2 degrees for every 1000 feet?
11 degrees
What is the answer if the temperature was 90 degrees below zero and dropped 24 degrees What is the new temperature?
114 degrees
The temperature was 3 degrees Celsiuse it falls by 7 degrees celcuies what temperature is it now?
-4 degrees Celsius
What temperature is the freezing temperature?
32 degrees Fahrenheit (or 0 degrees celsius) is the point of freezing.
How much hotter than normal body temperature is 50degrees celsius?
A normal body temperature is 37 degrees Celsius or 98.6 degrees Fahrenheit. A body temperature of 50 degrees Celsius is 13 degrees hotter than a normal body temperature. If your body temperature were to reach 50 degrees Celsius you be dead.
Why the brass need to be immersed in the boiling water before place it in the calorimeter?
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.
What are the limitations of saparating and throttling calorimeter?
There must be at least 10 degrees of superheat in the calorimeter for accurate results.
What is the average room temperature in kilograms?
The kilogram (kg) is a unit of mass, and cannot be applied to temperature. However, room temperature is generally regarded as 20 degrees Celsius, which is 68 degrees Fahrenheit, or 293 kelvins.
How is heat measured in a calorimeter?
An insulated container with a thermometer to measure change of heat can be used as a calorimeter. Example a polystyrene cup with a lid.
What is Measured using a thermometer?
Heat is measured using calorimeter.A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.
A 0.43 kilogram block of iron initially has a temperature of 100.0 degrees C. It is allowed to cool until its temperature is 25.0 degrees C. How much thermal energy transferred to the sourroundings?
It is 15188 Joules.
How much energy must be added to 1 kilogram piece of aluminum with a specific heat of 900 J to increase its temperature from 20 degrees Celsius to 100 degrees Celsius?
90,000
A balloon contains a gas with a pressure of 580 mm Hg and a temperature of 227 degrees C What is the new pressure mm Hg of the gas when the temperature drops to 27 degrees C?
375mmhg
Meter that measures amounts of heat?
Unfortunately it is not the Calorimeter, which is used to measure energy, the measurement of the calorie was replaced by the Joule. The calorie/kilo-calorie was the measurement of the amount of energy need to cause a 1 degree temperature increase in one gram/kilogram of water. A Thermometer, which contains mercury that responds predictably to heat either by expanding or contracting, is the meter used for measuring the heat it is exposed to whether it be atmospheric, oceanic, direct heat or radiant heat, internal or external heat. A Thermometer measures heat or the lack of in Degrees on two different scales Centigrade and Fahrenheit.
