Question

What items are true about a block of ice at -10°C as you continue to apply heat

You can select more than one

1. It’s temperature will rise continuously until it completely melts
2. It’s temperature will rise until reaching 0°C
3. It’s temperature will not rise above -10°C until it melts
4. It’s temperature will remain at 0°C until all the ice melts

Answer 1

As heat is applied to a block of ice at -10°C, its temperature will increase until it reaches 0°C, then remain constant until the ice is fully melted; only after, the temperature of the water will rise.

Step-by-step explanation:

When applying heat to a block of ice at -10°C, the following phenomena will occur: First, the temperature of the ice will rise until reaching 0°C. Once the ice reaches 0°C, it will begin to melt, and during this melting process, the temperature will remain constant at 0°C. This is because the added heat is used to overcome the hydrogen bonds holding the water molecules in place, rather than increasing the temperature. Only after all the ice has melted, any further heat added will increase the temperature of the water.
