How can pathogens enter yogurt and how can this be prevented?
Pathogens can enter yogurt if unpasteurized milk was used and if the temperature was not brought up to temperature before inoculating the milk with the yogurt cultures. Spoilage of the milk would occur if the temperature was not brought to 80 degrees celsius for 15 minutes. Pathogens also enter if food handling procedures are misused or if there are unsanitary practices. This all can be prevented by proper temperatures, proper food handling and hand washing practices.
What is temperature and heat?
Heat is the energy transferred from one body to another as the result of a difference in temperature. Heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy results in an increase in the temperature of the colder body and a decrease in the temperature of the hotter body. Temperature is a measure of the average energy of the molecules of a body. It is expressed in terms of any of several scales, such as Fahrenheit, Celsius, or Kelvin.
What is the relationship between specific heat and the change in temperature of a substance?
Specific heat is the amount of energy it takes to raise a unit mass of the substance by one degree Celsius. For each unit of specific heat applied to a substance its temperature will increase by a set amount.

Ignition temperature for of steel is normally around 800degC.
Why did the world change from the Fahrenheit to the celsius scale?
Celsius makes better sense in chemistry, and the majority of the world uses it. I was brought up thinking in Fahrenheit degrees so I continue to use it. In conversations with friends around the world this causes confusion for me and my friends abroad. Starting to think in Celsius for younger people would be beneficial to them in the long run.

Which water freezes first boiling water cold water or room temperature.?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.

Temperature.
What is a supperconductor?
A metal is said to be a superconductor if it has some resistance at room temperature, but when it is brought down to a critical temperature; i.e. to a very low temperature such as 20 K, it loses its resistivity completely. Also, a superconductor expels out any magnetic field inside of it that it had at room temperature, and is not affected by any further field applied to it at its cooler temperature.
