Haya, twende tukasuluhishe maswali haya.

12. (a) Figure 4 below shows a setup used to investigate the relationship between volume and temperature of a fixed mass of dry air at constant pressure.

i) State the measurements that should be taken in the experiment.
Vipimo vinavyopaswa kuchukuliwa katika jaribio hili ni:

• Joto (temperature) la hewa kavu (kutoka kipimajoto).
• Urefu (length) wa safu ya hewa kavu (kutoka kwenye mizani), ambayo inawakilisha ujazo (volume) wa hewa.

ii) List two functions of the sulphuric acid index.
Kazi mbili za kiashiria cha asidi ya sulfuriki ni:

• Kufunga kiasi kisichobadilika cha hewa kavu.
• Kuzuia hewa iliyofungwa kutoroka kutoka kwenye bomba.
• Kudumisha shinikizo la hewa kuwa la mara kwa mara ndani ya bomba.
• Kufanya kazi kama wakala wa kukausha ili kuhakikisha hewa iliyofungwa inabaki kavu.
