Answer:

The correct option is;

(b) 0.8 Tm

Explanation:

Sintering is a form of heat treatment given to introduce a material in powdery form in order to introduce the properties of integrity and strength

by the application of heat to the powder at a temperature below its melting point.

With regards to imparting favorable metal properties in the metal to undergo sintering such as ductility, toughness, porosity, hardness, strength it is required to select a sintering temperature higher than 0.6 - 0.8 Tm.

When the sugar cubes are <span>placed in water, then, the mixture will be affected by stirring the water. 
By stirring the water, the sugar cubes dissolve in water. The molecules of sugar cubes interact with water molecules in the jar. But when more sugar is added to the water, there comes a saturation point when no more sugar will be dissolved and it will settle down. Then, by raising the temperature the settled sugar will be dissolved too.</span>

user100 [1]

Answer

Depends on type of mixture. But I think separating the different sized particles through filtration would be a sufficient answer for middle school level unless they have taught you about other mixtures.

Explanation:

Hey,

There are thousands of way to separate mixtures. Each way is specific to the type of mixture. If the mixture is homogeneous processes like distillation can be employed. For heterogeneous mixture filtration can be used to separate particles of different sizes.

How do protons in the nucleus behave?
IRISSAK [1]

Answer:

Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (mesons), binding them together. Once they are bound, it takes considerable energy to break them apart.
