Answer:
I found this don't know if its any use or not
<span>Evaporation involves a liquid becoming a gas and sublimation is the change of a solid directly to a gas.Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing.</span>
Malleability is the <span>property characterized by the ability to bend.

Malleability is the quality of something that can be shaped into something else without breaking. It <span>is a physical property of metals that defines the ability to be hammered, pressed, or rolled into thin sheets without being broken.</span>
Answer:
8 time increase in K.E.
Explanation:
Consider Mass of truck = m kg and speed = v m/s then
K.E. = 1/2 ×mv²
If mass and speed both are doubled i.e let m₀ = 2m and v₀ = 2v then
(K.E.)₀ = 1/2 ×2m(2v)²
(K.E.)₀ = 8 (1/2 × mv²) = 8 × K.E.
