______ is a way to slow down the reactions that spoil milk
Answer:
b. keeping milk cold
Explanation:
The cool temperature in the fridge will stop it from going to any further reactions so it won't get spoilt
d. Keeping milk warm can help in slowing down of the reaction that can spoil milk.
Pasteurization can be defined as the heat treatment process in which the heat is provided to a liquid for example milk to prevent the growth of microbes which are least resistant to the heat. This process destroy the microbes, their spores, and also prevent their colonization.This process is useful in preventing soreness of milk and extends its shelf life. Keeping milk in cold container, in a cold temperature, or away from other sources of food will not help in slowing down the reactions that spoil milk.Hence, d. Keeping milk warm can help in slowing down of the reaction that can spoil milk.

does water in a glass have mass
Answer:
A glass of water, or 200 grams of water, therefore contains 6.6855 × 1024 water molecules. The total mass of the hydrosphere is about 1.4 × 1024 grams, and thus the total hydrosphere contains about 7 × 1021 glasses of water (with 200 grams of water in each).
Explanation:
Answer:
Just like solids, liquids also have their own characteristic density. ... Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter. The density of a substance is the same regardless of the size of the sample.
Matter is generally defined as any thing that has mass and occupies spaces. Matter is generally divided into three categories ; solid, liquid and gas. Water is a liquid, water has does have molecules, thus has a mass, and is suspended in an area such as water in glass.
SO YES WATER IN A GLASS HAS MASS :)Hope this helps ~OwO~

Does Kumiho the legendary exist??
Answer: Deriving from ancient Chinese myths and folklores, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful woman often set out to seduce boys, and eat their liver or heart (depending on the legend).
Hoped that helped!
Answer:
No
Explanation:
The Kumiho is similar to other fox creatures, such as the Japanese kitsune and Chinese Huli jing. Even though they have similar magical abilities and longevity, Kumiho is more malevolent than other fox spirits. Of these long-lived legendary creatures, the Kumiho is the only fox that kills and eats humans. Kumiho is just a myth itś not real and no one has seen this fox so "it" does not exist.

Answer:
If you mean "What is a hypothesis and the scientific law?" than hypothesis means a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation and scientific laws or laws of science, are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Answer:
If you mean "What do hypothesis and scientific law have in common" than a hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept.
