Acopper cube with a mass of 100 grams is heated in a boiling water bath to 100.0 celsius. the cube is removed from the bath and placed on a very large block of ice which is at a temperature of 0.00 celsius. what is the maximum mass of ice that could conceivably be melted by the heat exchange, assuming all the thermal energy is used to melt the ice? the specific heat of copper is 0.39 j/g-c and the enthalpy of fusion for water is 334 j/g.

The copper cube has a mass of 11.68 grams

Explanation:

Step 1: Data given

Mass of the copper cube = 100 grams

Temperature of water = 100°C

Temperature of ice = 0°C

Specific heat of copper = 0.39J/g°C

Enthalpy of fusion of water = 334 J/g

Step 2:  Calculate the energy for cooling the copper

energy in the copper as it cools from 100º to 0º = 0.39 J/g°C * 100g *100°C = 3900 J

Step 3: Calculate the mass of the copper cube

3900 J / 334 J/g = 11.68 grams

The copper cube has a mass of 11.68 grams

M = 3900/334 = 11.68 g

change is 3900 J

yes they ca   is ur ansswerrr

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
