Does the heat from the alloy transfer to the water in the setup equation

In summary, the problem involves finding the specific heat of an alloy that was heated to 86.6 degrees Celsius and then placed in a calorimeter with 61.2 grams of water at 19.6 degrees Celsius. After the alloy was added, the temperature of the water rose to 21.3 degrees Celsius. The formula used to solve for the specific heat is c = 250*(61.2)/(21.3 * ?) where 250 represents the mass of the alloy (25.0 grams), 61.2 represents the mass of the water, and 21.3 represents the change in temperature of the water. However, there is a missing value that needs to be determined in order to solve for the

This is the problem:
An alloy of mass 25.0 grams was heated to 86.6 C
and then placed in a calorimeter that contained 61.2 grams of water at 19.6 C
The temp of the water rose to 21.3 , determine the specific heat of the alloy in J/gC

Is this the correct way to set it up?

c = 250*(61.2)/(21.3 * ?)

Can you define each of 250, 61.2 and 21.3 in your result here. My suspicion is that you're wrong, but until I see what you mean by each of these numbers I remain unsure.
 

1. How does heat transfer occur between an alloy and water?

When an alloy and water are in contact with each other, heat transfer occurs due to the temperature difference between the two substances. The heat from the alloy, which has a higher temperature, flows to the water, which has a lower temperature, until both substances reach thermal equilibrium.

2. What factors affect the heat transfer between an alloy and water in the setup equation?

The rate of heat transfer between an alloy and water is influenced by several factors, including the temperature difference between the two substances, the surface area of contact, the thermal conductivity of the materials, and the thickness of the substances.

3. Does the heat transfer between an alloy and water depend on the type of alloy used?

Yes, the type of alloy used can affect the rate of heat transfer to water. Different alloys have different thermal conductivities, which determine how well they can transfer heat to other substances. Some alloys, such as copper and aluminum, have high thermal conductivity and can transfer heat more efficiently compared to others.

4. Can the heat transfer between an alloy and water be controlled?

Yes, the rate of heat transfer between an alloy and water can be controlled by adjusting certain factors. For example, the temperature difference between the two substances can be altered, or the thickness of the substances can be changed to affect the rate of heat transfer.

5. How can the heat transfer between an alloy and water be measured?

The rate of heat transfer between an alloy and water can be measured using a thermometer. By measuring the temperature change of the water over a specific time period, the rate of heat transfer can be calculated using the formula Q = mcΔT, where Q is the heat transferred, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.
