DURING THE TRANSFORMATION OF MATTER FROM THE SOLID TO THE LIQUID STATE, THE HEAT SUPPLIED DOES NOT PRODUCE A TEMPERATURE INCREASE BECAUSE
A. the heat energy is quickly conducted away B. the heat capacity has become very large as the substance melts C. the heat gained is equal to the heat lost by the substance D. all the heat is used to break the bonds holding…
EXPLAIN WHY IT IS NOT ADVISABLE TO HEAT AMMONIUM DIOXONITRATE (III) DIRECTLY
Ammonium dioxonitrate (III), also known as ammonium nitroxylate or ammonium nitrite, is a chemical compound with the formula NH4NO2. It is a white crystalline solid that is highly reactive and can decompose explosively under certain conditions. Due to its instability,…
A HEATING COIL IS RATED AT 70 W, CALCULATE THE TIME IT WILL TAKE THIS COIL TO HEAT 1.4 KG OF WATER AT 30°C TO 100°C
To calculate the time it will take for a heating coil to heat a given amount of water, we can use the formula: Q = mcΔT where Q is the heat energy transferred, m is the mass of the water,…
LATENT HEAT CONCEPT
Introduction Latent heat is the amount of heat energy that is required or released to change the state of a substance without changing its temperature. It is called “latent” because the heat energy involved is not apparent in the temperature…
