Answer:
i added this table for some help
Explanation:
here are some examples
<u>metals:</u>They are hard and shiny, strong, and easy to shape. They are used for many industrial purposes. This group includes iron, gold, silver, chromium, nickel, and copper, some of which are also noble metals.
<u>non-metals:</u>a chemical element (as boron, carbon, or nitrogen) that lacks the characteristics of a metal and that is able to form anions, acidic oxides, acids, and stable compounds with hydrogen.
<u>metalloids:</u>Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. Metalloids have mixed properties which are difficult to characterize.
Answer:
the specific heat capacity of ethanol is 2.4608 J/g°C
The variation in the final temperature is due to the rate of heat lost. Calorimeters do not dissipate or absorb energy
Explanation:
the solution is in the attached Word file
Considering the direct relationship between pressure and temperature, the new pressure in the bicycle tire would be 63.01 psi
<h3>Gas law</h3>
The general gas laws is given by:
P1V1/T1 = P2V2/T2
Where P1 = initial pressure V1 = initial volume T1 = initial temperature, P2 = final pressure, V2 = final volume, and T2 = final temperature.
In this case, P1 = 100 psi, V1 = 1, T1 = 19+273 = 292, P2 = ?, V2 = 1.4, T2 = 58+273 = 331
P2 = P1V1T2/T1V2
= 100x1x292/331x1.4
= 63.01 psi
