All metals except potassium and sodium, have a property known as malleability. Malleability is the quality of something that can be shaped into something else without breaking. So when aluminium and copper are hammered they will not break. Rather they will change shape and become thin or flat at the area where its hammered.

All Non- metals except diamond are brittle in nature, so when we hammer it , they will break down into pieces. So when ice and glass will be hammered they will shatter into pieces.

A train travels 70 kilometers in 1 hours, and then 63 kilometers in 2 hours. What is its average speed?
lozanna [386]
The answer is:  " 44 \frac{1}{3} km " ; 
                              or; write as:  " 44.333 km " .
___________________________________________________________
Explanation:
___________________________________________________________
(70 km + 63 km) ÷ (2 + 1 ) =  133 km ÷ 3 =  " 44 \frac{1}{3} km "  ; 
                                                                            or; write as:  " 44.333 km " .

evablogger [386]

A fixed container containing an ideal gas is heated. The pressure of the gas increases because the molecules move faster.

You can speed up the motion of the molecules in a gas by heating it. The pressure will rise and there will be greater impacts on the container's walls.

The container walls are pressed against by the combined force of the collisions. The energy you provide when you heat the gas makes the gas's particles more kinetically energetic and put more pressure on the container.

As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

Suppose you could suddenly increase the speed of every molecule in a gas by a factor of 2. Would the gas pressure increase by a
Elena L [17]

<h2>The pressure will become double </h2>

Explanation:

The gas pressure is directly proportional to the mean root square velocity of the constituent molecules of gas .

P ∝ \sqrt{\frac{C_1^2+C_2^2+C_3^2----C_n^2}{n} }      I

Here C₁ , C₂ ------------ Cₙ is the velocities of molecules .

By making these velocities double

The pressure P₀ ∝ 2\sqrt{\frac{C_1^2+C_2^2+C_3^2----C_n^2}{n} }          II

By dividing II by I

P₀ = 2 P

Thus pressure will become double than its previous value
