Particles begin to move out of their ordered arrangement due to energy. They are unable to escape because of external pressure pushing down on the liquid.
Work = (force) x (distance)
To lift each baby, force = 90N,
distance = 1.0 something, let's say 1.0 meter .
Work to lift each baby = (90N) x (1.0 meter) = 90 joules.
Work to lift both of them = 2 x 90 joules = 180 joules.
Answer:
7.55 g
Explanation:
Heat of fusion = 333kj/kg
Heat capacity, c = 4190 j/kg /k
Heat capacity in j/g /k = 0.4190
Let the Number of grams of ice that will melt = n
Number of grams * heat of fusion = heat capacity * temperature change
n * 0.333 = 0.419 * (6-0)
0.333n = 2.514
n = 2.514 / 0.333
n = 7.5495
n = 7.55 gram
Hence, the number of gram of ice that will melt is 7.55 grams
