How much heat energy would it take to melt a 20 kg block of lead that was at 24 degrees Celsius?
1,277,800 j
How would you show that water is not a good conductor of heat?
A test tube is filled with tap water (about 25oC). An ice block is placed in the test tube and is kept at the bottom of the test tube by means of a wire gauze. Next (without delaying too much since the ice block would melt completely!), the test tube is bent and the upper end of the test tube placed in a Bunsen flame. It is found that the water at the upper end boils before the ice block melts. This shows that water is a poor conductor of heat.
How much heat does it take to melt 3 kg of helium?
63 kJ is needed.
How much heat is required to melt 5 kg of ice?
it depends how cold the ice is
How does a meltdown occur?
When fuel rods in a nuclear power plant generate too much heat, they start to melt.

Why is it necessary for the space shuttle to have a heat shield?
The friction created by the atmosphere of the Earth and the belly of the shuttle would create so much plasma that the metal would melt off and the shuttle would explode.
Why does shredded chocolate melt faster than whole chocolate?
Because the heat has a much larger surface area on which it can act upon to melt the chocolate
