0.385 Joules/Gram Celsius is the specific heat of copper. So,
q(Joules) = mass * specific heat * change in temperature
q = (200 g Cu)(0.385 J/gC)(30 C - 150 C)
= - 9240 Joules
-------------------------amount of heat dissipation ( answer can be positive )
The final temperature of the ice block can be calculated using the formula: Q = mcΔT, where Q is the heat removed, m is the mass of the ice block, c is the specific heat capacity of ice, and ΔT is the change in temperature. Given the data, you can find the final temperature of the ice block.
The block of ice will remain stable and maintain its temperature of 0 degrees Celsius as long as the room temperature is also 0 degrees Celsius. Both will eventually reach thermal equilibrium, but there will be no change in state or temperature of the ice as it melts since the room temperature is not warmer than the ice.
There's no reason to say that it always does that. It only does if it has more volumethan the copper block. If the copper block has more volume, then it displaces morewater than the iron block does.In fact, if you get a styrofoam block that's big enough, that can displace more waterthan your iron block OR your copper block. It just has to be big enough.
Using the specific heat capacity of aluminum (0.897 J/g°C), you can calculate the change in temperature using the formula Q = mcΔT, where Q is the heat absorbed (725J), m is the mass of aluminum block (55g), c is the specific heat capacity, and ΔT is the change in temperature. Rearranging the formula to solve for ΔT and substituting the values, you can then find the final temperature by adding the change in temperature to the initial temperature (27.5°C). Calculate and the final temperature of the aluminum block will be the sum of the initial temperature and the change in temperature.
A block of ice at 0C begins to change its temperature as it melts when it reaches 0C.
The final temperature of the ice block can be calculated using the formula: Q = mcΔT, where Q is the heat removed, m is the mass of the ice block, c is the specific heat capacity of ice, and ΔT is the change in temperature. Given the data, you can find the final temperature of the ice block.
The block of ice will remain stable and maintain its temperature of 0 degrees Celsius as long as the room temperature is also 0 degrees Celsius. Both will eventually reach thermal equilibrium, but there will be no change in state or temperature of the ice as it melts since the room temperature is not warmer than the ice.
The heat lost by the copper block equals the heat gained by the water and calorimeter. Using the heat equation, q=mcΔT, where q is the heat, m is the mass, c is the specific heat, and ΔT is the change in temperature, you can calculate the final temperature of the system as 26.2 degrees Celsius.
Thre temperature of the block of ice increases until you reach 0 degrees C when the block of ice begins to melt.
The final temperature of the rivets will be the melting point of ice (0 degrees Celsius) because the heat gained by the rivets (from their initial temperature of 100 degrees Celsius) will be used to melt the ice. Once all the ice is melted, the temperature will stabilize at 0 degrees Celsius.
No, copper cannot block magnetism. It is not a magnetic material, so it will not interfere with magnetic fields or block them.
Copper is the best conductor of electricity. It is in the d block.
To find the equilibrium temperature, we can use the principle of conservation of energy. The total heat lost by the copper block as it cools down should be equal to the total heat gained by the aluminum calorimeter cup and the water as they warm up. This can be calculated using the formula: mcΔT = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature. Once you solve this equation, you can find the equilibrium temperature at which heat transfer is balanced.
Iron is denser than copper, so a block of iron will displace more water than a block of copper of the same weight because the iron block takes up less space for the same mass. This means that the iron block will sink deeper into the water, displacing more water.
Yes, copper is a d-block element. It belongs to Group 11 of the periodic table and has an atomic number of 29, indicating that it has 29 electrons, with 10 of them being in the d orbital. Copper is known for its excellent electrical conductivity and is commonly used in electrical wiring and plumbing due to its properties.
The temperature on the moon varies from -233 Celsius (-387 Fahrenheit) at night to 123 Celsius (253 Fahrenheit) during the day. Because the moon has no atmosphere to block some of the sun's rays or to help trap heat, its temperature varies greatly between day and night.
Adding more copper to a copper block will increase its mass and volume, causing a change in its overall size and weight. It can also increase the thermal and electrical conductivity properties of the block. However, its physical appearance and chemical properties will remain the same.
