Answer the following question given this paragraph: Boiling Points When the vapor pressure increases enough to equal the external atmospheric pressure, the liquid reaches its boiling point. The boiling point of a liquid is the temperature at which its equilibrium vapor pressure is equal to the pressure exerted on the liquid by its gaseous surroundings. For liquids in open containers, this pressure is that due to the earth's atmosphere. The normal boiling point of a liquid is defined as its boiling point when surrounding pressure is equal to 1 atm (101.3 kPa). Figure 10.24 shows the variation in vapor pressure with temperature for several different. Q: What term is used to describe when a liquid is the temperature at which its equilibrium vapor pressure is equal to the pressure exerted on the liquid by its gaseous surroundings? Choices: - freezing point - burning point - evaporating point - boiling point A:
boiling point

The nonliving environment includes water, sunlight, soil, and other physical factors. Q: An ecosystem consists of all the living things and what? Choices: - living environment - phosphorescent environment - local environment - nonliving environment A:

Ques:Answer the following question given this paragraph: Like Earth, the Moon has a distinct crust, mantle, and core. The crust is composed of igneous rock. This rock is rich in the elements oxygen, silicon, magnesium, and aluminum. On the near side, the Moon's crust is about 60 kilometers thick. On the far side, the crust is about 100 kilometers thick. The mantle is made of rock like Earth's mantle. The Moon has a small metallic core, perhaps 600 to 800 kilometers in diameter. The composition of the core is probably mostly iron with some sulfur and nickel. We learned this both from the rock samples gathered by astronauts and from spacecraft sent to the Moon. Q: Like earth, the moon has a distinct crust, mantle, and what else? Choices: - temperature - polarity - atmosphere - core A:

Ans:core
Ques:Answer the following question given this paragraph: Birds also have wings that function as an aerofoil . The surface of the aerofoil is curved to help the bird control and use the air currents to fly. Aerofoils are also found on the wings of airplanes. Q: Where are aerofoils found? Choices: - airplanes and plants - birds and busses - birds and cars - birds and airplanes A:

Ans:
birds and airplanes
