What Do You Know About Specific Heat? Quiz

The letter "c" in the formula most likely stands for the specific heat of the substance. Specific heat is a property of a substance that represents the amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius. Therefore, it is reasonable to assume that "c" in the formula refers to the specific heat of the substance. The other options provided do not seem to be directly related to the concept of specific heat.

Water has a specific heat of 1 calorie/gram C=4.186 joule/gram. This means that it requires 4.186 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius. The specific heat of a substance is a measure of how much heat energy it can absorb or release without changing its temperature significantly. In the case of water, it has a relatively high specific heat compared to other substances, which means it can absorb or release a large amount of heat energy without experiencing a significant change in temperature.

Specific heat is the amount of heat energy required to raise the temperature of a substance by a certain amount. It is a property that is specific to each material and is measured in units of energy per unit mass per degree Celsius (or Kelvin). The correct answer states that specific heat is the amount of heat needed to raise the temperature of 1kg of some material, which accurately describes the concept of specific heat.

The correct answer is "the mass of the sample in grams." In scientific formulas, the letter "m" is commonly used to represent mass. In this particular formula, the value of "m" represents the mass of the sample in grams.

The correct formula for specific heat is q = c x m x t, where q represents the amount of heat transferred, c is the specific heat capacity of the substance, m is the mass of the substance, and t is the change in temperature.

The letter "q" in the formula represents the heat absorbed or released. This means that it can be used to calculate the amount of heat energy that is either gained or lost by a substance or system. It is a general term that encompasses both the heat absorbed and the heat released, making it a comprehensive representation of the heat transfer in a given situation.

Water has the highest specific heat because it requires a large amount of energy to raise its temperature compared to other substances. This is due to the hydrogen bonding between water molecules, which allows it to absorb and store more heat energy. As a result, water is able to regulate temperature and maintain stable conditions in various environments, making it an essential component for life on Earth.

The Dulong and Petit law states that the specific heat capacity of a substance is directly proportional to its atomic mass. This means that the specific heat capacity of a substance increases as the atomic mass increases. Therefore, the correct answer is "Dulong and Petit" because the specific heat capacity is related to this law.
