  • Rahul, a class 8 student conducted the following experiment and recorded the observations in the given table. The correct observation and inference drawn are

    A
    I, balloon has a higher ignition temperature than water hence, it explodes
    B
    II, water increases the melting point of balloon
    C
    III, water in the balloon absorbs the heat
    D
    II, water conducts the heat away from the balloon.

  • Sakshi performed two experiments as shown in figure 1 and 2, and recorded her observations in the table. Find out the correct observation and the reason behind it from the options given below.

    A
    I, paper has a higher ignition temperature than water.
    B
    II, fireproof paper pan is used in figure 2.
    C
    III, paper is non-inflammable.
    D
    II, heat supplied to the paper pan is transferred to water by conduction, so ignition temperature of paper is not reached in figure 2.
