Luas diukur dalam unit persegi: segi empat tepat l × w, segi tiga ½ × tapak × tinggi, bulatan π·r². Lilitan bulatan ialah π·d = 2π·r. Isi padu dalam unit padu: kuboid l × w × h, silinder π·r²·h. Gunakan nilai π yang diberikan oleh soalan.
Jawapan: T = 374 °F
Skala suhu: °F = °C × 9/5 + 32 dan °C = (°F − 32) × 5/9. Perubahan suhu ditukar tanpa 32, kerana 32 hanya menganjak titik sifar: perubahan 1 °C ialah perubahan 1.8 °F.

Jawapan: D · It falls, so air flows in
At constant temperature, a larger volume means a lower pressure. The pressure inside the lungs falls below atmospheric pressure, so air moves in. This is inhalation.
Jawapan: C · H–F
Fluorin ialah unsur yang paling elektronegatif, jadi ikatan H–F mempunyai perbezaan keelektronegatifan yang paling besar. H–H dan Cl–Cl tak berkutub, dan C–H hampir tak berkutub.
