A piece of titanium at 100.0°C was dropped into 50.0 g of water at 20.0°C. The...
please help me. Thanks A piece of copper metal weighing 36.3 g is initially at 100.0 degree C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0 degree C. After stirring, the final temperature of both copper and water is 25.0 degree C. Assuming no heat losses, an that the specific heat capacity of water is 4.184 J/g degreeC, what is the specific heat capacity of the copper in J/g degreeC?
A piece of metal of mass 35.0 g at 100.0°C was placed in 150.0 g of water at 20.0 °C. After stirring, the final temperature of the water and the metal is 23.8°C. What is the specific heat capacity of the metal? (specific heat capacity for H2O = 4.184 J/g °C) O-0.89 J 8°C 19.6 J/g °C 1.96J/g °C O 0.89 J/g °C
A hot piece of aluminum weighing 50.0 grams at 350°C is dropped into 500. grams of water at 22.0°C. What is the final temperature of the water? The specific heat of aluminum is 0.902 J/g°C and that of water is 4.184 J/g°C.
A 275-g sample of nickel at 100.0°C is placed in 100.0 g of water at 22.0°C. What is the final temperature of the water? Assume no heat transfer with the surroundings. The specific heat of nickel is 0.444 J/g·°C and the specific heat of water is 4.184 J/g·°C. Hint: The final temp for both the system and surroundings will be the same.
5) If 78.6 g piece of iron is dropped into 100.0 g of water initially at 24.6 °C. The final temperature of both water and iron was measure at 28.5 °C. Calculate the initial temperature of iron? (Specific heat of water and iron from #1)
1. A 20.0-8 piece of aluminum at 0.0°C is dropped into a beaker containing 100.0 g of water. The temperature of the water drops from 90.0°C to 85.7°C. What quantity of energy did the aluminum absorb? What is the specific heat of the aluminum? 2. If 55.0 ml of water at 22.5°C is mixed with 100.0 ml of water at 95.2 'C, what would you expect for a final temperature? 3. Cold packs (the kind that get cold when you...
3) If 28.0 g of water at 26.4 °C gain 5,563 J of heat, what is the final temperature of water? (Specific heat of water is 4.184 J/g.°C)) 4) If 46.2 g piece of aluminum is cooled from 84.5 °C to 29.5 °C, how much energy was lost by aluminum? (specific heat of aluminum is 0.901 J/(g.°C)) 5) If 78.6 g piece of iron is dropped into 100.0 g of water initially at 24.6 °C. The final temperature of both...
A 50.0-g piece of iron at 152 C is dropped into 20.0 g H20(I) at 90 C in an open, thermally insulated container How much water would you expect to vaporize, assuming no water splashes out? The specific hoats of
A 28.8 g piece of iron and a 20.7 g piece of gold at 100.0°C were dropped into 630.0 mL of water at 19.0°C. The molar heat capacities of iron and gold are 25.19 J/(mol·°C) and 25.41 J/(mol·°C), respectively. What is the final temperature of the water and pieces of metal?
2. DANS A piece of unknown metal weighs 100.0 g. It is heated to 98.0°C before it was dropped into a calorimeter containing 50.0 g of water at 22.0°C. The final temperature was observed to be 26.4'C. Calculate the specific heat capacity of the metal. Type your answer
