compare the boiling point of water at sea leavel to the boiling point in denver (altitude = 1 mile) Explain
steposvetlana [31]

Answer:

boiling point decreases in denver

Explanation:

in higher places

theres less atmospheric pressure

it takes less energy to bring water to the boiling point.

Less energy means less heat

which means water will boil at a lower temperature

The pH scale is used to measure the degree of acidity or alkalinity of a solution. The scale runs from 0 (very acidic solutions can have a negative pH) to 14 (very alkaline solutions can have a pH higher than this), while a neutral liquid such as pure water has a pH of 7. The pH is linked to the concentration of hydrogen ions (H +) in the solution. Diluting an acid or alkali affects the concentration of H +<span> ions in a solution and therefore affects the pH. In this activity, we will investigate how diluting an acid or alkali affects the pH.

Answer:

d=1.5\ g/cm^3

Explanation:

Given that,

The mass of the rock, m = 15 g

The volume of the rock, V = 10 cm³

We need to find the density of the rock. The density of an object is equal to the mass per unit volume such that,

d=\dfrac{m}{V}\\\\d=\dfrac{15\ g}{10\ cm^3}\\\\d=1.5\ g/cm^3

So, the density of the rock is equal to 1.5\ g/cm^3.

Select the correct answer. What is heat of vaporization? A. It is the heat required to change a substance’s temperature by 1°C.
Luba_88 [7]

D. It is the heat required to change a gram of substance from a liquid to a gas.

Explanation:

The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.

  • It is also known as the enthalpy of vaporization.
  • The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
  • This heat of vaporization is dependent on the pressure conditions the process is taking place.
  • Different liquids have their heat of vaporization.
