Milk contains bacteria that cause tuberculosis and other diseases. When milk is heated to 85c, all of the tuberculosis bacteria and disease causing bacteria are killed, and most of the bacteria are killed that causes milk to spoil. So, it makes milk safe to drink. The process is called Pasteurization. That technique greatly reduced tuberculosis in the United States making it much lower than in places where people use raw milk.
The specific heat capacity of milk is around 3.93 J/g°C.
The amount of heat required can be calculated using the formula Q = mcΔT, where Q is the heat energy, m is the mass of water (250 grams), c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the change in temperature (85°C - 10°C = 75°C). Plugging in the values, the heat required is approximately 78,750 Joules or 78.75 kJ.
c = 18u + 85 c - 85 = 18u (c - 85)/18 = u
Milk that has been heat treated to destroy any pathogenic (harmful) bacteria as well as some of the spoilage bacteria. This heat treatment is a minimum of 72°C for 15 seconds or equivalents thereof such as 63°C for 30 minutes.
The answer will depend on the thermal capacity or heat capacity of the metal.
what percentage of a mike carton comes from paper A. 85% B. 40% C. 20% D. 92%
Milk is pasteurised at 63°C for 30 minutes (batch pasteurisation) or at 72°C for 15 seconds (High Temperature Short Time [HTST]). These heat treatments are equally effective.
85°F is equivalent to 29.4°C in Celsius.

It saved millions from terrible diseases like Yellow Fever, Plauge, and Rabies.Louis Pasteur also invented Pasteurization, which is when you heat milk at a certain tempature(60 degrees C- 65 degrees C)This kills the bactiria in the milk,andeother beverages.
Microwaving milk can lead to a reduction in its nutrient content, particularly vitamins like vitamin C and B vitamins. This is because the heat from the microwave can break down these nutrients. It is recommended to heat milk on the stove or in a microwave-safe container to minimize nutrient loss.
