Answer all questions in this section.Jawab sernua soalan dalam bahagian ini.

A student carries out an experiment to investigate the relationship between the increase

in temperature, Afl of water and the mass, nr, of the water. The initial temperature, 9s,

of a basin of water was rneasured with a thermometer as shown in Diagram 1.1.

Searang pelajar menjalanknn satu elcsperimen untuk menyiasat hubungan antarakcnailrsn suhu, L0 bagi air denganjisim, m, air itu. Suhu awal, 06, bagi sebuah besen

air diukur oleh sebush termometer seperti dituniukkan dalam Rajah 1.1.

Diagram l.l lRajahl.l,

A mass, m: 0.20 kg of the water taken from the basin was placed in a polystyrene cup

and heated for 1 minute as shown in Diagram 1.2. The final temper&ture, B, of thewater is read on the thermometer. Diagram 1.3 shows the meniscus of the mercurycolumn in the thermometer.

Suatujisim, m = 0.20kgbagi air daripada besen itu diletakkon di dalam sebuah cowanpolisterina dan dipanaskan selama 1 minit seperti ditunjukkan dalam Raiah 1.2. Suhu

akhir, 0, bagi air itu diuhr oleh sehuah termometer. Rujah L.3 menunjukkan meniskus
