How much energy must be added to a 2kg piece of wood with a specific heat capacity of 1760 JkgoC to increase its temperature from 10oC to 50oC?
Its 900 joules to raise the temperature of 1Kg of the substance by a degree, and we have 2Kg, to heat out sample we need 1800 J to raise the temperature by one degree celsius.
we need to heat the sample by 40 degrees and if we need 1800 J per degree then
40 x 1800 = 72000 J needed. Or 72KJ

Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
The size of a temperature increase in a substance depends primarily on?
The size of a temperature increase in a substance primarily depends on the amount of heat energy added to the substance and its specific heat capacity. The specific heat capacity determines how much energy is needed to raise the temperature of a substance by a certain amount.
Heat capacity is the characteristic of a material to?
absorb heat energy without undergoing a large increase in temperature. It is the amount of energy required to raise the temperature of a substance by a certain amount. Heat capacity is an extensive property and depends on the mass and specific heat capacity of the material.
Which would take more energy to increase temperature by 5 degrees water or Aluminum?
It would take more energy to increase the temperature of water by 5 degrees than aluminum. This is because water has a higher specific heat capacity, meaning it requires more energy to raise its temperature compared to aluminum.
What term describes how much energy it takes to change the temperature of the substance?
specific heat capacity
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 concrete brick aluminum or copper take most energy to increase its temperature?
Copper will take the most energy to increase its temperature, followed by aluminum and then concrete brick. This is because copper has a higher specific heat capacity compared to aluminum and concrete brick, meaning it requires more energy to raise its temperature.

What three factors affect thermal energy?
raising of object temperature, the mass, specific heat
How does the temperature of 33 grams of graphite change when it absorbs 350 joules of thermal energy?
The temperature of graphite will increase because it absorbs thermal energy. The temperature increase can be calculated using the specific heat capacity of graphite.
The size of a temperature increase in a substance depends primarily on?
The size of a temperature increase in a substance primarily depends on the amount of heat energy added to the substance and its specific heat capacity. The specific heat capacity determines how much energy is needed to raise the temperature of a substance by a certain amount.
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
What are the factors that determine the amount of energy needed to raise the temperature?
The amount of energy needed to raise the temperature of a substance depends on its mass, specific heat capacity, and the desired temperature increase. The formula to calculate this is: Q = mcΔT, where Q is the energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change.
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.
Which substance in Table 5.2 requires the smallest amount of energy to increase the temperature of 52.0 of that substance by 15?
To determine which substance in Table 5.2 requires the smallest amount of energy to increase the temperature of 52.0 g by 15°C, you need to look for the substance with the lowest specific heat capacity. The energy required can be calculated using the formula ( Q = mc\Delta T ), where ( Q ) is the heat energy, ( m ) is the mass, ( c ) is the specific heat capacity, and ( \Delta T ) is the temperature change. Therefore, the substance with the lowest specific heat capacity will require the least energy for the specified temperature increase.
If sand has a specific-heat capacity of 835 JkgC how much energy must be added to a 2kg pile of it to increase its temperature from 40C to 50C Show your work?
To calculate the energy required to increase the temperature of the sand, you can use the specific heat capacity formula: Energy = mass x specific heat capacity x change in temperature. Plugging in the values: Energy = 2kg x 835 J/kg°C x (50°C - 40°C) = 16700 Joules. Therefore, 16700 Joules of energy must be added to the 2kg pile of sand to increase its temperature from 40°C to 50°C.
Effect of temperature on specific heat of material?
An increase in temperature generally causes the specific heat of a material to decrease. This is because as temperature rises, the vibrational energy of the material's molecules also increases, leading to less energy needed to raise the temperature of the material. Conversely, as temperature decreases, the specific heat of a material tends to increase.
