While camping up at Haloooo Mountain (5,500 feet above sea level), it generally takes Sandy about the same amount of time to boil water for her soup as it takes to make a sandwich. This week, Sandy is camping at a trail that is only about 200 feet above sea level. Sandy is very hungry and wants something to eat immediately. Should she make the soup or sandwich? Which would be ready more quickly and why?

Answers

Answer 1
Answer: She should make soup. When you are way above sea level, the atmospheric pressure decreases. Boiling starts when the vapor pressure of the liquid is the same with the atmospheric pressure. This would mean that water boils at a much lower temperature than the usual 100deg C. So it would take longer for the components in the soup to cook compared to when it is cooked on the foot of the mountain.

How do we know that caramelizing sugar is a chemical change ?

Answers

Chemical transformation: it's all transformation changes the composition of matter, i.e. that matter produces a new substance with different initial properties burning sugar to make caramel, we cannot retrieve the initial sugar.

An example of an atom that has no charge is one that hasA. 1 proton, 2 electrons, and 3 neutrons.
B. 3 protons, 1 electron, and 3 neutrons.
C. 2 protons, 2 electrons, and 1 neutron.
D. 3 protons, 2 electrons, and 1 neutron.

Answers

For an atom to have no charge, that is neutral, the number of electrons should be the same to the number of electrons. If the number of electron is more than the number of proton, the atom is negatively charged. Also, when the number of proton is more than the number of electron, the atom is positively charged. The answer to this item is letter C.
An atom consists of a postively charged nucleus that is surrounded by a negatively charged cloud of electrons . The nucleus consists of positvely charged protons and charge-neutral neutrons. An example of an atom that has no net charge is one that has two protons, two electrons and one neutron (Answer C).

_____ is a process that helps fuel your metabolism.Deoxidation
Oxidation
Glycolysis
Hydrolysis

Answers

Glycolysis is a process that helps fuel your metabolism. It is apart of cellular respiration the process that helps produce ATP.

Explanation:

Glycolysis is the metabolic process that assists as the grounds for both aerobic and anaerobic cellular respiration. In glycolysis, glucose is transformed into pyruvate. Glucose is a six-membered circle molecule found in the blood and is regularly a result of the breakdown of carbohydrates into sugar.

Glycolysis is the process that helps fuel your metabolism. It generates energy in the form of ATP through the breakdown of glucose.

The metabolic process that helps fuel your body is known as Glycolysis. This is a series of reactions that takes place in the cell's cytoplasm, where glucose (a simple sugar) is broken down into two molecules of pyruvate. This process generates energy which gets stored in the form of ATP (adenosine triphosphate), a molecule that allows the body to perform various functions like muscle contraction, nerve impulse propagation, and chemical synthesis, etc. Hence, glycolysis supports the metabolism by providing necessary energy to the body.
