Which of the following most closely typifies the sintering temperatures in PM? (a) 0.5 Tm, (b) 0.8 Tm, (c) Tm, where Tm = meltin

SashulF [63]

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.

Mg(s) + 2 HCl (aq) _MGCL2 (Aq) + H2 (g) the total pressure of gas collected over water is 740.0 mmhg and the temperature is 21.5

Julli [10]

The pressure of hydrogen gas formed is 720.8 mmHg.

<h3>What is Partial Pressure ?</h3>

The pressure exerted by a (specified) component in a mixture of gases.

We have to understand one thing that the Hydrogen, which is collected over water, will be mixed with water vapor.

This means that the total pressure of the mixture will have two components.

the partial pressure of Hydrogen

the vapor pressure of water at 21.5 C

The vapor pressure of water at that temperature is approximately

19.231 mmHg.

This means that

$\rm P_{total} = P_{hydrogen} + \; P_{water vapor}$

740 = $\rm P_{hydrogen}$ + 19.231

$\rm P_{hydrogen}$ = 740-19.231

$\rm P_{hydrogen}$ = 720.8 mmHg

Therefore the pressure of hydrogen gas formed is 720.8 mmHg.
