[SPM Physics Pressure] (form 5)

Help me again :sob: friends ā€¦ Iā€™m really stuck :pray::pray::pray:

Question

21 Pada 27^{\circ} \mathrm{C}, sebiji belon kaji cuaca mempunyai tekanan 100 \mathrm{kPa}. Apabila belon itu mencapai ketinggian tertentu, tekanan berkurang kepada 95 \mathrm{kPa}. Berapakah suhu pada ketinggian itu?
At 27^{\circ} \mathrm{C}, a weather forecast balloon has a pressure of 100 \mathrm{kPa}. As the balloon reaches a certain altitude, the pressure decreases to 95 \mathrm{kPa}. What is the temperature at the altitude?
A -12.0^{\circ} \mathrm{C}
B 12.0^{\circ} \mathrm{C}
C 25.7^{\circ} \mathrm{C}
D 65.7^{\circ} \mathrm{C}

Answer

Hi Dhaksheina,
For this question, we will assume that the volume is constant. Then, we would use Pressure Law to solve this question. (Note: Temperature must be converted to the SI unit Kelvin)
