A student left a bar of chocolate in the sun on a hot day. As the chocolate melted, which property changed?

1 answer:

7 0

The property changed was its weight

The melted chocolate weighs the same, has an identical mass, and is still composed of chocolate.

Now it’s just melted chocolate instead of a candy bar and has thus changed shapes.

How do the wavelength and frequency of red light compare to the wavelength and frequency of blue light?

11111nata11111 [884]

Answer:

Red light has a longer wavelength and lower frequency than blue light.

Explanation:

The photon energy carried by the red light is lower than blue light. The higher the frequency of the photon, the greater its energy and the greater its wavelength, the lower its energy. Thus, red light has a longer wavelength and lower frequency than blue light.

How much heat transfer (in kcal) is required to raise the temperature of a 0.850 kg aluminum pot containing 2.00 kg of water fro

hram777 [196]

To solve this problem we will apply the concept related to the heat transferred to a body to reach a certain temperature. This concept is shaped by the energy ratio of a body which is the product of the mass, its specific heat and the change in temperature. For the specific case, it will be the sum of the heat transferred to the Water, the Aluminum and the loss due to latency due to vaporization in the water. That is to say,

$\Delta Q = m_{Al} C_p \Delta T +m_wC_w \Delta T +m_w L_v$
