What is specific heat?
- A.
Heat from the sun.
- B.
The amount of heat needed to to raise the temperature at room temperature.
- C.
The amount of heat needed to raise the temperature of 1kg of some material.
- D.
The heat needed to restore room temperature.
- E.
None of the above
Correct Answer
C. The amount of heat needed to raise the temperature of 1kg of some material.Explanation
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.Rate this question:

What is the formula for specific heat?
- A.
Q=c+m
- B.
T=m+c xq
- C.
Q=cx m x t
- D.
T =mxn+x
- E.
None of the above
Correct Answer
C. Q=cx m x tExplanation
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.Rate this question:

The specific heat of water is ?
- A.
1 calorie/gram C=1.846joule/gram
- B.
1 calorie/gram C=4.186joule/gram
- C.
1 calorie/gram C=8.416joule/gram
- D.
1 calorie/gram=1.648joule
Correct Answer
B. 1 calorie/gram C=4.186joule/gramExplanation
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.Rate this question:

What does the q stand for in the formula?
- A.
The heat lost
- B.
The heat that escapes from something
- C.
The heat absorbed or released
- D.
All of the above
Correct Answer
C. The heat absorbed or releasedExplanation
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.Rate this question:

What does the c stand for in the formula?
- A.
The heat lost from the substance
- B.
The specific heat of the substance
- C.
The energy from the substance
- D.
None of the above
Correct Answer
B. The specific heat of the substanceExplanation
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.Rate this question:

What does the m stand for in thje formula?
- A.
The volume of the sample in liters
- B.
The volume of the sample in millimeters
- C.
The mass of the sample in grams
- D.
The mass of the sample in kilograms.
Correct Answer
C. The mass of the sample in gramsExplanation
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.Rate this question:

What law does specific heat relate to?
- A.
Einstein-Debye
- B.
Dulong and Petit
- C.
Both of these laws
- D.
None of these laws
Correct Answer
B. Dulong and PetitExplanation
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.Rate this question:

What substance has the highest specific heat?
- A.
Water
- B.
Metal
- C.
Dirt
- D.
Sand
Correct Answer
A. WaterExplanation
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.Rate this question:
