Answer:
Well, Aluminum Oxide has a very high melting point. Carbon dioxide has a very low boiling point.
Explanation:
They are both talking about different things, melting and boiling. Aluminum Oxide's melting point is much higher then carbon dioxide's melting point. Hope this help, and good luck on your assignment (if one)
Answer:
856,68 J/gram
Explanation:
We know that the variaton of temperature of 1K is equal to 1°C
so if the ΔT is 3.55°C, it is 3.55K.
so
403 J - 1 K
x - 3.55K
X= 403 * 3.55 = 1430,65 J
1.670 g - 1430,65 J
1 g - y
y = 
= 856,68 J
Answer:
Paraffin oil is used for determination of boiling point and melting point for the following reasons: It has a very high boiling point and so it can be used to maintain high temperatures in the boiling and melting point apparatus without loss of the substance.
Answer:
The pennies are NOT made of pure copper since the obtained density is 9.29 g/cm3 which is greater than the density of copper which is 8.96 g/cm3.
