It is transferred by conduction when two objects at two different temps touch each other, and the one with the most heat will transfer its heat to the cooler object until they both have the same temperature..
At the point of touching the fast moving molecules of the warmer object will collide with the slower moving molecules of the cooler object.
<span>No. A chemical reaction does not destroy matter but it can convert matter into another form or into a substance with a different molecular structure. Matter can even be converted into energy in a nuclear reaction.</span>
Answer:
Material is less dense than water so it will float in water.
Explanation:
Given data:
Mass of material = 110 g
Volume of material = 312 cm³
Will it float or sink in water = ?
Solution:
First of all we will calculate the density of material.
d = m/v
d = 110 g/ 312 cm³
d = 0.35 g/cm³
The density of water is 1 g/cm³ it means material is less dense than water so it will float in water.
