Answer:
A)from deep within the earth
Explanation:
Answer:
a. 4900 mL; b. 4900 cm³ c. 4.9x10⁻³ m³
Explanation:
1 L = 1 dm³
4.9 L = 4.9 dm³
1 dm³ = 1000 cm³ → 4900 cm³
1 cm³ = 1 mL (4900 mL)
1 dm³ = 1x10⁻³ m³ → 4.9x10⁻³ m³
Answer:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range.
(2) The rate of heating does not matter.
Explanation:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range, because varying temperature range across the body will lead to inaccurate determination of melting point.
(2) In principle, the melting temperature is INDEPENDENT (not dependent) on the heating rate. so in other words, altering the heating rate does not affect the measure of melting point.
Answer: 50 grams
Explanation: The water is still only going to be 50 grams. Although it’s in a different state, it didn’t gain or lose any water while being frozen.
