A thermacole’ icebox is a cheap and efficient method for storing small quantities ofcooked food in summer in particular. A cubical icebox of side 30 cm has a thickness for5.0 cm. If 4.0 kg of ice is put in the box, estimate the amount of ice remaining after 6 hr.The outside temperature is 45 0 C and co-efficient of thermal conductivity of thermacoleis 0.01 J . [ Heat of fusion of water = 335 ]

ABC Question 14Students in Mr. Jackson's class built two containers designed to keep ice cold for a long period of time.  Both containers had the same dimensions, but were constructed from different materials.  They put one piece of ice in each container, kept the surrounding temperature constant, and measured how long it took for each piece of ice to melt.  The table shows their results. Container NumberTime It Took The Ice to Melt          1                           252 32 Which container was most likely made with a material that had a low specific heat?A Container 1 because it took the shortest amount of time for the ice to melt, and materials with low specific heat are poor insulators.B Container 1 because it took the shortest amount of time for the ice to melt, and materials with low specific heat are good insulatorsC Container 2 because it took the longest amount of time for the ice to melt, and materials with low specific heat are poor insulators.D Container 2 because it took the longest amount of time for the ice pop to melt, and materials with low specific heat are good insulators.

Ice cubes of a total mass 80 g, and at 0 0C, are put into a chocolate drink of mass 275 g. All the icemelts as 25300 J of thermal energy transfers from the chocolate drink to the ice. The finaltemperature of the drink is 0 0C.(i) Calculate the specific latent heat of fusion for ice.

The thermal energy that causes the ice to melt is transferred from the chocolate drink as itcools. The loss of this thermal energy causes the temperature of the 275 g of chocolate drinkto fall by 15 0C. Calculate the specific heat capacity of the chocolate drink.specific heat capacity=
