    When two surfaces rub against each other, they slow  down as energy is lost as ________. - ProProfs

    When two surfaces rub against each other, they slow  down as energy is lost as ________.

    • Cold

    • Heat

    • Friction

    • Air pressure

    Correct Answer
    A. Heat
    Explanation
    When two surfaces rub against each other, they slow down as energy is lost as heat. Friction between the surfaces causes the generation of heat, which leads to a decrease in the kinetic energy of the objects in motion. This heat energy is a result of the conversion of mechanical energy into thermal energy due to the resistance encountered during the rubbing process.

    When you add a 100 ml of a strong base to 5ml of a weak acid the pH value would most like be what pH?

    • 2pH

    • 12pH

    • 4pH

    • 7pH

    Correct Answer
    A. 12pH
    Explanation
    When a strong base is added to a weak acid, it results in a reaction that neutralizes the acid. This is because the strong base has a higher concentration of hydroxide ions (OH-) compared to the weak acid's concentration of hydrogen ions (H+). The reaction between the base and acid forms water and a salt. The excess hydroxide ions from the base increase the concentration of hydroxide ions in the solution, leading to a higher pH value. A pH of 12 indicates a highly basic solution, which is consistent with the addition of a strong base to a weak acid.

    The main cause of all weather is the_________.

    • Sky

    • Atmosphere

    • Sun

    • Moom

    Correct Answer
    A. Sun
    Explanation
    The sun is the main cause of all weather because it provides the energy that drives the Earth's weather systems. The sun's heat warms the Earth's surface, causing air to rise and creating areas of high and low pressure. This pressure difference leads to the movement of air, creating wind patterns. The sun also plays a crucial role in the water cycle, as it evaporates water from oceans, lakes, and rivers, which then condenses to form clouds and eventually falls as precipitation. Therefore, the sun's energy is essential in driving the Earth's weather patterns.
