The answer is either 38 g or 40.g KCLO3. If it 95% instead of 895%.
The only option that fits is the last one — improper and biased measurements.
A scientist should be able to estimate a measurement to a tenth of the smallest scale division. The millimetre ruler would give an uncertainty of ±0.1 mm. The inch ruler would give an uncertainty of ±0.1 in. Since 1 in = 25.4 mm, 0.1 in = 2.54 mm. Thus, the <em>millimetre ruler is more precise</em> than the inch ruler.
Converting units <em>does not</em> change the degree of precision of a measurement.
The first scientist <em>did not</em> convert the units (the second scientist did!).
BUT, having different team members make the observations could introduce uncertainties caused by improper or biased readings of the equipment.
Answer:
3 °C
Explanation:
The pressure is constant, so this looks like a case where we can use Charles’ Law:
Invert both sides of the equation.
Multiply both sides by <em>V</em>₂
<em>V</em>₁ = 13.3 L; <em>T</em>₁ = (55 + 273.15) K = 328.15 K
<em>V</em>₂ = 11.2 L; <em>T</em>₂ = ?
Answer:
I think it's the state of the surrounding water because if the water holds impurities it will float and if it doesn't have impurities it will sink
