Kurt Cobain was a musician and songwriter, best known as the lead vocalist and guitarist of the American rock band Nirvana. He was born on February 20, 1967, and sadly passed away on April 5, 1994. Cobain's contributions to music and his impact on popular culture have made him an influential figure in rock history.
The option that measures the average kinetic energy of the particles in a substance is temperature. To understand how temperature is related to the average kinetic energy, you can consider the kinetic theory of gases. According to this theory, the temperature of a substance is directly proportional to the average kinetic energy of its particles.
To measure the temperature of a substance, you can use a thermometer. A thermometer contains a temperature-sensitive material such as mercury or alcohol that expands or contracts depending on the temperature. By observing the expansion or contraction of the material, we can determine the temperature. Common temperature scales used are Celsius, Fahrenheit, and Kelvin.
So, to find the measure of the average kinetic energy of the particles in a substance, you need to measure its temperature using a thermometer.
