Will the same mass of iron and water require the same amount of heat to increase their temperature the same number of degrees?
No, no. Of course not. The amount of heat Q required to increase the temperature of a body of mass m having specific heat capacity c through DO degrees celsius is given by: Q = mcDO Thus, the one with the higher specific heat capacity will require more heat energy.
Which have lowest specific heat capacity?
They will be the same because the molecular structure of the tea is the same as the molecular structure of water. The added tea to water does not affect the molecular structure of water.
Does a substance that cools off quickly have a high or low specific heat capacity?
Specific heat capacity is the amount of energy required to increase the temperature of an object or substance by 1oK. The rate at which something cools is proportional to the difference in temperature between the object and its surroundings. Consequently, neither has any relation to the other.
Does it take more energy as heat to raise the temperature of water by one degree than to raise the temperature of steam by the same amount?
Yes. The specific heat capacity of liquid water is 4.184 J/g•oC, and the specific heat capacity of steam is 2.010 J/g•oC.
Why hot water is more dangerous than hot air of the same temperature and mass?
Hot water has higher specific heat capacity compared to air, meaning it can store more heat energy. This results in hot water having more potential to transfer heat to the body upon contact, causing burns. In contrast, hot air has lower specific heat capacity and cannot transfer heat as effectively as water, making it less dangerous at the same temperature and mass.
What are the factors upon which the amount of heat contained in a body depends?
The amount of heat contained in a body depends on its mass, temperature, and specific heat capacity. The more massive a body is, the more heat it can store for the same temperature change. Additionally, materials with a higher specific heat capacity require more heat to raise their temperature.
What is a penny's specific heat capacity?
Specific heat capacity is heat capacity per unit mass. So it depends on the exact alloy composity of your penny, and not on its size.In a typical US post-1962 penny, the specific heat capacity is about .39 kJ/kgKIn a US penny from 1864-1962, the specific heat capacity would be a little less than this. The same was true from 1837-1857.From 1793-1837, the specific heat capacity was about .39 kJ/kgK.
Four 5gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to determine which block will increase its temperature t?
The block with the lowest specific heat capacity will experience the greatest increase in temperature. Since specific heat capacity measures the amount of heat energy required to raise the temperature of a substance, the block with the lowest specific heat capacity will heat up faster with the same amount of heat energy absorbed. Therefore, the metal block with the lowest specific heat capacity will experience the greatest temperature increase.
Will the same mass of iron and water require the same amount of heat to increase their temperature the same number of degrees?
No, no. Of course not. The amount of heat Q required to increase the temperature of a body of mass m having specific heat capacity c through DO degrees celsius is given by: Q = mcDO Thus, the one with the higher specific heat capacity will require more heat energy.
Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to determine which block will increase its temperature t?
To determine which block will increase its temperature the most, compare the specific heat capacity of each metal. The metal with the lowest specific heat capacity will increase its temperature the most with the same amount of heat energy absorbed. Choose the metal with the lowest specific heat capacity among the four blocks.
What is the predicted result when two different materials of equal mass absorb the same amount of energy by heat flow?
The material with lower specific heat capacity will experience a greater temperature increase compared to the material with higher specific heat capacity when absorbing the same amount of energy by heat flow.
Would two different liquids stored in the fridge for the same period of time be equally cold?
No. They would lose (or absorb) the same amount of heat, but their temperatures would be different.Every liquid has a unique specific heat capacity.The specific heat capacity of a substance is the amount of heat required to heat unit mass (1 kg) of that substance through 1°Celsius.So, liquids with different specific heats would show different change in temperature after losing the same amount of heat.For example, a liquid with a lower specific heat capacity would require lesser heat to change it's temperature while one with a higher specific heat capacity would require more heat.Hence, since the heat lost would be the same, the liquid with a lower specific heat capacity would cool more and have a lower temperature.
The molar heat capacity of gaseous hexane at 25 degrees Celsius is 142.6 J What is the specific heat?
Specific heat capacity is an intrinsic property of a substance and is independent of the amount of the substance. Therefore, the specific heat capacity of gaseous hexane would be the same as its molar heat capacity, which is 142.6 J/mol°C.
Can two body at same temperature have different heat?
Yes, two bodies at the same temperature can have different amounts of heat because heat is a measure of the total thermal energy contained within an object. The amount of heat a body has depends on its mass and specific heat capacity, regardless of its temperature.
How will the masses of the two objects affect the final temperature?
The masses of the objects will affect the final temperature based on their specific heat capacities. If two objects with different masses and the same heat input have different specific heat capacities, the object with the lower specific heat capacity will tend to have a higher final temperature compared to the object with the higher specific heat capacity. This is because the object with the lower specific heat capacity requires less heat to raise its temperature.
Is it possible for two different materials to have the same heat capacities?
Yes, it is possible for two different materials to have the same heat capacities. Heat capacity is an intrinsic property of a substance that depends on its mass and specific heat capacity. Therefore, materials with different compositions can still have the same heat capacity if their mass and specific heat capacities are appropriately matched.
Which have lowest specific heat capacity?
They will be the same because the molecular structure of the tea is the same as the molecular structure of water. The added tea to water does not affect the molecular structure of water.
