If 20.2kJ of energy is added to 5.0g of water at 95 degrees C, calculate the...
if 48.0 grams of water at 78.0 degrees C is added to 75.0 grams of water at 42.0 degrees Celsius what is the final temperature?
show all work please! 1. A piece of hot lead is added to cold water in a constant volume calorimeter . The lead loses 3450 J of heat and the water gains 2890 J of heat. Calculate the mass of lead added if the initial temperature of the lead (0.158 J/g- degrees C) is 98 degrees C and the final temperature is 37 degrees C 2. Calculate the heat capacity of the calorimeter if the initial and final temperature of...
Suppose you want to cool 0.760 L (0.760 kg) of water initially at 31.8 degrees C by adding ice cubes whose initial temperature is 0.0 degrees C. What mass of ice must be added so that the final temperature of the system is 8.10 degrees C? Assume that no heat is lost to the surroundings.
A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celsius is added to 50.00 grams of water initially at 12.16 degrees Celsius. The final temperature of the metal and water is 20.15 degrees Celsius. Calculate the specific heat of the metal. (The specific heat of water is 4.184 J/g*C). (HINTS: Recall that the q of a system is equal to the -q of the surroundings. So you can set up two equations here: one for the loss...
7. What mass of steam at 122 °C must be added to 2.20 kg of ice at-25.0 °C to yield liquid water at 90.0°F? Show all your work--equations, units, conversions, etc.
How much energy is required to turn 5.00 kg of ice at -25.0 degrees C to steam at 140 degrees C? Show your work. cice = 2090 J/kg•oC Lfusion (water) = 3.33 x 105 J/kg cwater = 4186 J/kg•oC Lvapor(water) = 2.26 x 106 J/kg csteam = 2010 J/kg•oC
A 25.00 gram sample of an unknown metal initially at 99.0 degrees Celsius is added to 50.00 grams of water initially at 14.37 degrees Celsius. The final temperature of the metal and water is 20.15 degrees Celsius Calculate the specific heat of the metal (The specific heat of water is 4.184J'g'C). (HINTS Recall that the qof a system is equal to the of the surroundings So you can set up two equations here one for the loss of heat from...
26.0 g steam at 120 °C is added temperature of the resulting water 120 g of ice at -10 °C in an insulated container. What is the final temperature of the resulting water?
Exactly 19.5 mL of water at 27.0 °C is added to a hot iron skillet. All of the water is converted to steam at 100.0°C. The mass of the skillet is 1.45 kg. What is the change in temperature of the skillet? Answer should be in degrees Celsius
Calculate the energy released when 50.0g of steam condenses at 100℃.Use the cooling curve to show what happens when 50.0g steam condenses at 100℃ and then cools to 20℃.
