Original Recipe
1 (18 1/4 ounce) Box devils food cake mix
1/2 cup vegetable oil
2 large eggs
Confectioners' Sugar (for rolling)

Directions:
Preheat oven to 350 degrees. Stir (by hand) cake mix, oil, and eggs- until dough forms. Dust with sugar and shape into 1 inch balls. Roll balls in sugar and place on ungreased cookie sheet. Bake 8-10 minutes. Remove from pan after one minute and put on cooling rack.

According to recent research, ice skaters are able to glide smoothly across the ice because A. ice is constantly subliming to form a layer of water vapor B. a thin, liquid-like layer of water covers the ice C. pressure from the skates raises the melting point of ice D. pressure from the skates lowers the melting point of ice

Answer:

B. A thin, liquid-like layer of water covers the ice

Explanation:

Hello,

Ice skaters are able to glide smoothly across the ice because a thin, liquid-like layer of water covers the ice, this is achieved due to the environmental conditions which allow the liquid water layer to coexist with the ice. Due to this fact, the liquid-like layer diminishes the friction coefficient between the ice skateboard and the ice allowing the slip to be carried out smoothly.

Best regards.

At what temperature is the average speed of oxygen molecules equal to 1.12×104m/s?

 we will use the root mean squared speed of oxygen formula
v= (3RT) / M
T= vM/3R
where
v =1.12x104 m/s; velocity
R=  (8.31447 kg m2 s-2 K-1 mol-1) gas constant

M = 0.0319988 kg/mol; molar mass of oxygen

substituting the given values, we will get 

T(K)= 14.37K or -258.78 C

Oxygen molecules speed of 1.12x104 m/s is at temperature -258.78C.

QUESTION POSTED AT 28/02/2020 - 04:26 PM

What happens to the temperature of water between the time ice melts and water boils (this is partially quoted from a question)? Also, what change occurs in temperature after water starts boiling (this is also from a booklet)? Thank you and please explain your thoughts. This is based on the phase changes of water, and you should refer to a graph on the phase changes of water.

Your first statement is very ambiguous so I will give it the best shot as to what you are saying.
The temperature, between the point of ice melting and water boiling, is increasing as water is in its liquid state.
Now during a phase change, or while the water is boiling, the temperature remains constant because the energy being added is being consumed to complete the phase change.
But if you're looking at the phase change graph, the points of positive slopes, are moments when energy is increasing as the water, in whatever state, is increasing. But when the slope of the graph is 0, the water is changing phases and the temperature remains constant! I hope I explained that so you could understand it, and I hope this helps you!

What is process of bringing water to boiling affects

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. There are two main types of boiling; nucleate boiling where small bubbles of vapour form at discrete points, and critical heat flux boiling where the boiling surface is heated above a certain critical temperature and a film of vapor forms on the surface. Transition boiling is an intermediate, unstable form of boiling with elements of both types. The boiling point of water is 100 °C or 212 °F, but is lower with the decreased atmospheric pressure found at higher altitudes.

Boiling water is used as a method of making it potable by killing microbes that may be present. The sensitivity of different micro-organisms to heat varies, but if water is held at 70 °C (158 °F) for ten minutes, many organisms are killed, but some are more resistant to heat and require one minute at the boiling point of water. Clostridium spores can survive this treatment, but as the infection caused by this microbe is not water-borne, this is not a problem.

Boiling is also used in cooking. Foods suitable for boiling include vegetables, starchy foods such as rice, noodles and potatoes, eggs, meats, sauces, stocks and soups. As a cooking method it is simple and suitable for large scale cookery. Tough meats or poultry can be given a long, slow cooking and a nutritious stock is produced. Disadvantages include loss of water-soluble vitamins and minerals. Commercially prepared foodstuffs are sometimes packed in polythene sachets and sold as "boil-in-the-bag" products.
