What will the final temperature be if 688 calories of heat is released by 25 mL of water with an initial temperature of 80 degrees celsius?
Do some converting first. 688 calories (4.184 Joules/1 calorie) = 2878.592 Joules 25 ml of water = 25 grams q(Jolules) = mass * specific heat * (Temp. final - Temp. initial) 2878.592 Joules = 25 grams Water * 4.180 J/gC * (Temp Final - 80C ) 2878.592 Joiles = 104.5( Temp. Final) - 8360 11238.592 =104.5(Temp. Final) 107.55 Celsius Final Temperature ( call it 108 C )
When 45g of an alloy at 25 are dropped into 100.0g of water the alloy absorbs 956 j of heat. If the final temperature of the alloy is 37 what is its specific heat?
1.77
A hot metal bar is placed into cool water what statement is true?
The temperature of the metal bar decreases.The temperature of the cool water increases.The final temperature of the metal bar will be the same as the final temperature of the water.
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.
How to calculate delta temperature?
To calculate the delta temperature, you will take the difference between the final and initial temperature.
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 final temperature of water if a metal is dropped in to it?
This would depend on the temperature of the water before you add the metal and what type of metal it is. if its copper it absorbs heat fast and would not change the temperature much but if you dropped lead into it then it would have to absorb more heat making the temperature lower than the copper. There are too many variables to answer the question.
What substance is used as the standard against which you measure specific heats?
If you can measure 3 of these 4 things then you can use this formula q( energy in Joules ) = Mass * specific heat * temperature final - temperature initial
What quantity is measured by calorimeter?
Final Temperature Initial Temperature Specific Heat Capacity of Calorimeter Plug the values into the equation: q = C( Tf - Ti ) , where C = specific heat, Tf = Final Temperature, and Ti = Initial Temperature.
What equipment is used to refine copper?
Copper is refined in a smelter. Then once raw copper is obtained the final purification is via electroplating.
What is the amount of heat required to change the temperature of 200.0 grams of aluminium to 10 degrees Celsius?
Q=m.c.Δt (m: mass, c: specific heat capacity, Δt :change in temperature)(specific heat capacity of aliminum is 0.90 J/K.g = 200 x 0.90 x 10 (if initial temperature is 0)(if not, then Δt=final temperature-initial temperature) =1800 Joules
Calculate the final temperature when 50 ml of water at 80?
When allowed to stand for long enough, the final temperature will reach room temperature.
