Question

400g each of water, oil and sand are taken and heated from room temperature to 700 C on identical Bunsen burners. The time taken for each to reach that temperature is noted. Heating is then stopped and the time taken for each to cool to room temperature is noted. Which of these will be true?

Answer 1

Answer:

One of the major effects of heat transfer is temperature change: heating increases the temperature while cooling decreases it. We assume that there is no phase change and that no work is done on or by the system. Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.

Answer 2

400g each of water, oil, and sand are taken and heated from room temperature to 700 C on identical Bunsen burners. The time taken for each to reach that temperature is noted. Heating is then stopped and the time taken for each to cool to room temperature is noted.

• Substances that take more time to get heated will take more time to cool.
• One of the significant impacts of heat transfer is temperature change: warming builds the temperature while cooling diminishes it.
• We expect no stage change and no work is done on or by the framework.
• Tests show that the transferred heat relies upon three factors—the adjustment of temperature, the mass of the framework, and the substance and period of the substance.
