Answer the following question given this paragraph: Viscosity measures a fluid's resistance to flow the higher the viscosity, the slower the flow of the material. One factor that affects viscosity is the strength of the intermolecular forces in the material. Molecules that exhibit higher intermolecular forces tend to have higher viscosities. Temperature also influences viscosity. A higher temperature results in a decrease in viscosity, since molecules are moving faster and the intermolecular forces are more easily disrupted. Most cooking oils are more viscous than water, but when heated, the viscosity decreases and the oil spreads more easily. Motor oils are ranked by viscosity. Lower viscosity oils provide less drag on the engine, but they are also used up faster than a higher-viscosity material. Q: What measures a fluid's resistance to flow? Choices: - elasticity - density - surface tension - viscosity A:
(Answer)
viscosity

The reaction is called a neutralization reaction. Q: When an acid and base solutions react, they produce water and a neutral ionic compound known as what? Choices: - sand - pollen - dirt - salt A:
(A).
salt
Ques:Answer the following question given this paragraph: Thermal energy can be trapped in Earth's atmosphere by gases such as CO2, water vapor, methane, and chlorofluorocarbons before it can be radiated into spacelike the effect of a greenhouse. It is not yet clear how large an increase in the temperature of Earth's surface can be attributed to this phenomenon. Venus is an example of a planet that has a runaway greenhouse effect. The atmosphere of Venus is about 95 times denser than that of Earth and contains about 95% CO2. Because Venus is closer to the sun, it also receives more solar radiation than Earth does. The result of increased solar radiation and high CO2 levels is an average surface temperature of about 450C, which is hot enough to melt lead. Data such as those in Figure 5.22 "Changes in Atmospheric CO" indicate that atmospheric levels of greenhouse gases have increased dramatically over the past 100 years, and it seems clear that the heavy use of fossil fuels by industry is largely responsible. It is not clear, however, how large an increase in temperature (global warming) may result from a continued increase in the levels of these gases. Estimates of the effects of doubling the preindustrial levels of CO2 range from a 0C to a 4.5C increase in the average temperature of Earth's surface, which is currently about. Q: Gases such as co2 and methane can trap what energy in earth's atmosphere, before radiating it into space? Choices: - mechanical energy - sunlight energy - potential energy - thermal energy A:

Ans:thermal energy
Answer the following question given this paragraph: Urethra The urethra transports urine from the bladder to the outside of the body for disposal. The urethra is the only urologic organ that shows any significant anatomic difference between males and females; all other urine transport structures are identical (Figure 25.3). Q: The urethra transports urine from what organ to the outside of the body for disposal? Choices: - heart - lungs - brain - bladder A:
bladder
