How Much Heat Must Be Removed to Make 3.1 kg of Shaved Ice at 0°C?

In summary, shaved ice thermodynamics involves the study of the physical and chemical processes that occur when making and consuming shaved ice. It includes understanding the properties of ice, such as its melting point and heat transfer, as well as the effects of various flavorings and additives on its texture and consistency. By applying thermodynamic principles, we can optimize the process of making and serving shaved ice to ensure the best taste and experience for consumers.

suppose that 3.1 kg of shaved ice is needed to keep medication cold in a room without a refrigerator. What amount o heat must be removed from the 3.1 kg of water to make ice once it has reached 0 deg C

You need to know the enthalpy of formation for ice. Unless it says at certain temperature and press ure use the formation for STP>
enthalpy of formation website:

another nice site with the enthalpy of fusion of ice on it:

What is the latent heat (at constant pressure,assumed atmospherical pressure,760 Torrs) for icing water/melting ice...?

FAQ: How Much Heat Must Be Removed to Make 3.1 kg of Shaved Ice at 0°C?

What is the definition of shaved ice thermodynamics?

Shaved ice thermodynamics is the study of the physical and chemical processes that occur when shaved ice is exposed to external factors such as temperature, pressure, and humidity.

How does temperature affect the melting rate of shaved ice?

As temperature increases, the molecules in shaved ice gain more energy, causing them to vibrate and move faster. This leads to a faster melting rate as the molecules break apart and change from a solid to a liquid state.

What is the role of pressure in shaved ice thermodynamics?

Pressure can affect the melting point of shaved ice. When pressure is applied, it can lower the melting point of the ice, causing it to melt at a faster rate. This is why shaved ice can quickly melt when held in warm hands.

How does humidity impact the texture of shaved ice?

Humidity can play a significant role in the texture of shaved ice. High humidity can cause the ice to stick together and form clumps, while low humidity can cause the ice to become dry and powdery. The ideal humidity for shaved ice is around 50-60%.

What are some applications of shaved ice thermodynamics?

Shaved ice thermodynamics has various applications, including the production and preservation of food, refrigeration and air conditioning systems, and the study of climate change. It is also used in the development of new materials and technologies related to temperature control and energy efficiency.
