Question

A 10.0 gram hook, with a specific heat of 0.40J/GC, is heated to red hotness in the flame of a bunsen burner. The hook is quickly dropped into 200.0 grams of water at 20.0C. If the temperature rises to 25.0C, then calulate the teamperature of the bunsen burner

Answer 1

To calculate the temperature of the Bunsen burner, we can use the principle of heat transfer and the equation Q = mcΔT. Using the given values, we can solve for Tb to find that the temperature of the Bunsen burner is approximately 1165°C.

Step-by-step explanation:

To calculate the temperature of the Bunsen burner, we need to use the principle of heat transfer. We can use the equation:

Q = mcΔT

Where Q is the heat transferred, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.

In this case, we can set up the equation like this:

(10.0g)(0.40 J/g°C)(Tb - 25.0°C)

= -(10.0g)(0.40 J/g°C)(25.0°C - 20.0°C) - (200.0g)(4.18 J/g°C)(Tb - 20.0°C)

Solving for Tb, we find that the temperature of the Bunsen burner is approximately 1165°C.
