Which of the following correctly describes the movement of fluids in convection currents? A. Heat flows from cooler portions to warmer portions. B. Cooler portions rise and warmer portions fall. C. Warmer portions rise and cooler portions fall. D. Cold flows from cooler portions to warmer portions. 3. Examine the picture below.

Where is heat primarily transferred by conduction? A. at point 2, where the hand touches the pot handle B. at point 1, where warm water rises and cooler water sinks C. at point 4, in the center of the fire as fuel burns D. at point 3, where heat energy from the fire moves through space 4. The following diagram shows a graphical representation of solid ice changing into water vapor. Use this diagram to determine which of the following statements is true. A. When solid ice melts or liquid water vaporizes, neither the internal energy nor the temperature changes. B. When solid ice melts or liquid water vaporizes, both the internal energy and the temperature change. C. When solid ice melts or liquid water vaporizes, the temperature changes, but the internal energy does not change. D. When solid ice melts or liquid water vaporizes, the internal energy changes, but the

temperature does not change. 5. Space shuttles are covered by a layer of special tiles to protect them from the extreme temperatures they encounter during orbit and atmospheric reentry. Two types of tiles are often used: LRSI tiles (Low-temperature Reusable Surface Insulation tiles) are white in color and used mainly on the upper surface of the shuttle, where temperatures do not exceed 650°C. The ability of these tiles to reflect light efficiently protects the shuttle from the Sun's radiation while in orbit. HRSI tiles (High-temperature Reusable Surface Insulation tiles) are black in color and used on the underside of the shuttle, where temperatures can rise to 1260°C. The ability of these tiles to absorb and radiate thermal energy quickly protects the shuttle during the searing heat of atmospheric reentry.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
