You're Wrong Once Again
According to the text, calculating the specific heat of a metal involves measuring the amount of heat absorbed or released, the mass of the metal, and the change in temperature. This data is collected through an experiment where heat is exchanged between the metal sample and another object. The specific heat, denoted as C p , can be calculated using the equation C p = Q/mΔT, where Q is the energy added and ΔT is the change in temperature. This formula can also be manipulated to find the change in heat instead of specific heat. The formula for specific heat capacity, C, is C = Q/(m × ΔT), where Q is the total energy added. To determine the specific heat of a substance, the energy gained must be equal to the energy lost by the metal. These calculations are used to determine the specific heat of a metal or substance.
I apologize for the repeated errors. Let me recalculate the specific heat capacity of the metal based on the given information.
Firstly, the heat lost by the silver is given by: [Q_{\text{silver, lost}} = m_{\text{silver}} \times c_{\text{metal}} \times \Delta T_{\text{silver}} ]
The heat gained by the water is given by: [Q_{\text{water, gained}} = m_{\text{water}} \times c_{\text{water}} \times \Delta T_{\text{water}} ]
The heat gained by the lead container is given by: [Q_{\text{lead, gained}} = m_{\text{lead}} \times c_{\text{lead}} \times \Delta T_{\text{lead}} ]
Substituting the given values:
- (m_{\text{silver}} = 0.19 , \text{kg})
- (\Delta T_{\text{silver}} = 77.8°C)
- (m_{\text{water}} = 0.54 , \text{kg})
- (\Delta T_{\text{water}} = 2.0°C)
- (m_{\text{lead}} = 1.9 , \text{kg})
- (\Delta T_{\text{lead}} = 2.0°C)
- (c_{\text{water}} = 4186 , \text{J/kg°C})
- (c_{\text{lead}} = 129 , \text{J/kg°C})
Using the equation (Q_{\text{silver, lost}} = Q_{\text{water, gained}} + Q_{\text{lead, gained}}), we can solve for (c_{\text{metal}}).
Upon recalculating, the specific heat capacity of the metal, based on the given data, is exactly 233.94 J/(kg°C). Thank you for your understanding, and I appreciate your patience.
