it's 80 calories per gram. so you'd have to multiple 80 by 30 and you'll get 2400.
No. Because 200 degrees Celsius is 392 degrees Fahrenheit, which is 228 degrees Fahrenheit lower than the 620 degrees Fahrenheit required to melt the lead.
Yes the melting and freezing points are the same.
Ice melts at 0 degrees Celsius = 32 degrees Fahrenheit
A very good substance for melting ice is table salt. This is because salt is highly soluble in water, and, as more NaCl dissolves in the water, the more this impurity will depress the melting point. Because the water's melting point will be depressed, it will start to melt above zero degrees Celsius. (I'm not sure this is the best substance to melt ice, I simply put it here because of its solubility in water; if anyone knows a more soluble salt, then that will probably melt ice better) Sand is also really good to melt ice

To melt 10 grams of ice at 0 degrees Celsius, it would require 80 calories of heat energy per gram, so a total of 800 calories (80 calories/gram * 10 grams = 800 calories) would be needed.
To melt ice, the energy required is known as the heat of fusion, which is 334 J/g. To convert this to calories, we need to divide by 4.184 J/cal. So, the total calories required to melt a 25g ice cube at 0 degrees Celsius would be 25g x 334 J/g ÷ 4.184 J/cal = 1991 calories.

The heat energy required to melt ice at 0 degrees Celsius is called the heat of fusion. For ice, the heat of fusion is approximately 334 J/g. To convert this to calories, divide by 4.184 J/cal, which gives you approximately 80 calories of heat energy needed to melt 10 grams of ice.
To melt 1.52 g of ice, you need to provide 6.4 calories of heat energy per gram of ice. Therefore, to melt a 1.52 g ice cube, you would need 9.73 calories of heat energy.
The temperature needed to melt rock depends on its composition. On average, rocks require temperatures of 600-1,300 degrees Celsius to melt. However, some types of rock, like granite, may require temperatures well above 1,300 degrees Celsius to melt completely.
To convert 4 kg of ice at 0 degrees Celsius to steam at 100 degrees Celsius, you would need to calculate the heat required to raise the temperature of ice to 0 degrees Celsius, melt the ice to water at 0 degrees Celsius, raise the temperature of water to 100 degrees Celsius, and then convert water to steam at 100 degrees Celsius. The total amount of heat needed can be calculated using the specific heat capacities and latent heats of fusion and vaporization of water.
460 calories. that sounds good, too bad im watching calories too
80 calories per gram (called the latent heat of fusion) 80 x 255.67 = 20453.6 calories
About -2 -0 as the snow will not melt and not be to hard to throw at people
0° Celsius is the temperature at which ice starts to melt.
