Mell What is the molar heat capacity of silver J mol C?
The molar heat capacity of silver is 25.35 j/mol C.
How do you calculate the heat capacity of silver?
We use the specific heat equation, which states that,
- q=mcΔT.
- Silver has a molar mass of 107.8682 g/mol . So here, we got:
- q=0.0945598425mol ⋅25.35 Jmol ∘C ⋅14∘C.
- ≈33.6 J.
What is the energy required to raise the temperature of 1 g of a substance by 1 C or 1 K?
specific heat
The specific heat is the amount of heat required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin.

What is the heat of combustion per gram of quinone?
-2700 kJ/mol
The molar heat of combustion of quinone is -2700 kJ/mol.
How much heat is required to raise the temperature?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
What is the heat required to raise the temperature of 1 gram of a substance by 1 C?
The specific heat capacity is the amount of heat required to raise 1 gram of a substance by 1 degree Celsius. For example, the specific heat of H2O(l) is 4.18 J/g ° C. The specific heat is the amount of heat required to raise the temperature of 1 g of substance by one degree Celsius or one Kelvin.
Which metal has the highest heat capacity?
Specific heat capacity: Aluminum 0.91 J/g°C Copper 0.39 J/g°C Silver 0.240 J/g°C Lead 0.160 J/g°C. Specific heat capacity means the amount of heat required to raise the temperature of 1 grams of substance by 1 °C.
What metal has a heat capacity of?
| Specific Heat Capacity of Metals Table Chart | ||
|---|---|---|
| Metal | Btu/(lb-°F) | Btu/(lb-°C) |
| Carbon Steel | 0.120 | 0.216 |
| Cast Iron | 0.110 | 0.198 |

How is the molar heat capacity of silver determined?
The molar heat capacity of silver is 25.35 J/mol*C. How much energy would it take to raise the temperature of 10.2 g of silver by 14.0 degrees C? We got: m = 10.2 g,c = 25.35 J mol ∘C,ΔT = 14∘C. So, let’s first convert that amount of silver into moles. Silver has a molar mass of 107.8682 g/mol. So here, we got:
How to calculate the energy required to raise the temperature?
To calculate the energy required to raise the temperature of any given substance, here’s what you require: The specific heat capacity of the material, #c# (which you can look up). This is the amount of heat required to raise 1 gram of that substance by 1°C. Here is a source of values of #c# for different substances:
How much energy does it take to heat water to 52 degrees?
it takes the same amount of energy to heat water from 48 degrees to 52 degrees as it takes to heat water from 58 degrees to 62. But when the state of water changes from solid to fluid (e.g. -2°C to + 2°C) or from fluid to gas (e.g. 98°C to 102°C) this does not hold true any more.
How is the specific heat of copper calculated?
Specific heat is measured in BTU / lb °F in imperial units and in J/kg K in SI units. What is the specific heat capacity value of copper? The specific heat of copper is 385 J/kg K. You can use this value to estimate the energy required to heat a 100 g of copper by 5 °C, i.e., Q = m x Cp x ΔT = 0.1 * 385 * 5 = 192.5 J.
