Explain in terms of particle behavior why smoke particles cause the detector alarm to sound
Smoke detectors are of many types but they rely on the principle of diffusion of smoke. Diffusion is the movement of particles from a region of high concentration to a region of lower concentration. Smoke particles move in what is known as Brownian motion.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
The answer is "<span>the quantity of heat that is required to raise 1 g of the sample by 1°C (Kelvin) at a constant pressure"</span>
1 kg ---------- 1000 g
4.84 kg ------ ?
4.84 x 1000 / 1 => 4840 g
D = m / V
7.86 =4840 / V
V = 4840 / 7.86
V = 615.77 cm³
1 cm³ ------------ 0.01 dL
615.77 ----- ?
615.77 x 0.01 / 1
= 6.1577<span> dL</span>
273g/25 mL = 10.92 (that's the density)
What has a density of 10.92 grams/mL? I don't know but I bet it's in your notes or on the worksheet.
