What is the specific heat capacity of meat?

At a temperature of 30 degrees Celsius, the specific heat capacity values of 3.42, 3.18, 3.01, 3.45, 3.36, and 3.06 kJ/kg. K were obtained for samples of minced beef meat, hamburger patties, soudjouk, minced turkey meat, turkey sausage, and turkey soudjouk.

How do you find the specific heat of food?

Perform a multiplication using the difference in temperature with the sample’s mass. Share the heat or the energy that was provided with the goods. The equation for C is as follows: Q / (T m).

What is the specific heat capacity of chicken?

The thermal conductivity of chicken bones is 0.265 W/mK, while the specific heat capacity of chicken bones is 2.021 kJ/kg.

What is the specific heat of a potato?

Water has a specific heat of 4.190 kilojoules per kilogram. Potatoes have a typical specific heat value of 3.39 kilojoules per kilogram (Hayes, p. 65).

What is the density of ground beef?

The density was found to range from 1.006 to 1.033 g/cm3 according to the measurements taken.

What is the specific heat of fish?

Calculations were done to determine the specific heat of several fishes using these numbers, and the results ranged from 0.74 to 0.91 Kcal / kg oC between 30 and 0 degrees Celsius. The specific heat of fish continues to drop even lower when the fish is chilled further.

What is the specific heat of Turkey?

After factoring in these figures as well as the mass of the water and turkey, I arrive at a specific heat capacity for the turkey of 6.018 joules per gram per degree Celsius.

What is the specific heat of bread?

TABLE 1

Parameter	Unit	Value
Specific heat of bread, control, CP	J/kg K−1	2,489
Specific heat of bread, containing guar gum, CP	J/kg K−1	1,640
Bread thermal conductivity, control, k	W/m K−1	0.18
Bread thermal conductivity, containing guar gum, k	W/m K−1	0.28

What is the specific heat of a peanut?

Specific heats of peanut pods, kernels, and shells increased linearly from 2.1 to 3.3, 1.9 to 2.8, and 2.7 to 4.1 kJ kg1 °C1, respectively, with a corresponding increase in moisture content from 5.2 to 23.7, 5.0 to 30.6, and 3.5 to 28.7 percent. Peanut pods had the lowest specific heat of the three peanut components (d.b.).

What is the specific heat of cheese?

Cheese has a specific heat capacity of 3270 J/kgoC, whereas the crust has a capacity of 2800 J/kgoC.

What is the specific heat of rice?

Rice has a specific heat of 0.782 kilojoules per kilogram per degree Celsius, while chaff has a specific heat of 1.2 kilojoules per kilogram per degree Celsius.

What is the heat capacity of an egg?

Model parameters

	Value
Specific heat capacity (J/kg °C)	Yolk	3120
White	3800
Egg shell	888
Surface heat transfer coefficient (h) (W/m2 °C)	–	2072b

What is the specific heat of milk?

In light of the fact that the specific heat of milk fat, whether solid or liquid, is approximately 2.177 J/g K, Fox and McSweeney (1998) hypothesized that the specific heat of milk and cream would be strongly influenced by their fat content, particularly in the cases of those with a low water content.

What is the specific heat of spaghetti?

Pasta that has been dried out has a specific heat capacity of 1.8 joules per gram Celsius. Let’s say you put one pound (454 g) of pasta that was originally kept at 25 degrees Celsius into two liters of water that was kept at 95 degrees Celsius.

What is the specific heat of butter?

As can be seen in Figure 2, the specific heat capacity of butter that has been completely frozen was determined to be 1.8 kilojoules per kilogram kelvin-1.
