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.

Determine why the ice melted on the aluminium plate faster than on the plastic plate.

Cathy hypothesizes that plastic foam insulates cold drinks better than metal or ceramic materials do. To testthe hypothesis, she fills cups made from these materials with equal amounts of cold water. She records thetemperature of the water in each cup, using scientific thermometers, every 10 minutes until the waterreaches room temperature. Which of these conditions must be the same for this experiment to be valid?Group of answer choicesThe thermometer that is in each cupThe material of each cupThe ending temperature of the water in each cupThe starting temperature of the water in each cup PreviousNext

Look at the image below. Molly boils some water and pours it into a beaker. She records its temperature, covers it for 5 minutes, and then records its temperature again. She repeats this experiment with two different types of insulating material: newspaper and bubble wrap. Her results are below. Which beaker had the highest thermal energy after 5 minutes?

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 ]

Look at the image below. Molly boils some water and pours it into a beaker. She records its temperature, covers it for 5 minutes, and then records its temperature again. She repeats this experiment with two different types of insulating material: newspaper and bubble wrap. Her results are below. If she repeated this investigation with no lids on the beakers, would the temperatures after 5 minutes be higher, lower, or the same?
