Question

$A 4 kilogram$block of ice is removed from a freezer where its temperature was maintained at –$20 degrees$ Celsius. How much heat does the ice absorb as it is warmed to – 10 degrees? (The specific heat capacity of ice is 2,000 joules per kilogram degree Celsius.) no copied answers wrong answers will be reported

Answer 1

Answer:

Explanation:

(Specific heat of ice = 0.5 caVgmOC and L= 80 caVgm) consume to produce 1.75 x 104 kcal/min. 4 Solution: Heat required to rise the temperature of Heat per min = 1.75 x 10 m 3/min :=1.73m 3/min 10080 100 gm ice from -15°C to O°C:= 100 x 0.5 x 15:= 750ca1 S And if 1.73 m gas consume in one minute then in 6Q And heat required to melt the 100 gm ice at DoC, in water at O°C is minute the gas amount will

Answer 2

If 1,000 J of heat is absorbed by a 2 kg block of lead then the temperature of the ... Brick will take much longer to heat up and cool down
