How does heat differ from temperature
Sholpan [36]
<span>Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.</span>

A gas occupies 4.31 liters at a pressure of 0.755 atm. Determine the volume if the pressure is increased to 1.25 atm. (Boyle)
vlabodo [156]

Answer:

<h2>2.60 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{4.31 \times 0.755}{1.25}  =  \frac{3.25405}{1.25}  \\  = 2.60324

We have the final answer as

<h3>2.60 L</h3>

Hope this helps you

How does a conclusion differ from an inference?
Setler79 [48]

Answer:

the difference between the two. Inference: Inference is something that uses facts to determine other facts. ... Inference can be accurate or inaccurate, justified or unjustified, logical or illogical. Conclusion: A conclusion is the next logical step in the information series.

Explanation:

Inferences and conclusions from that analysis can be powerful tools for understanding people and the decisions that they make. An inference is an assumed fact based on available information. A drawn conclusion is an assumption developed as a next logical step for the given information.

compute the mass-specific enthalpy change associated with Nz that is undergoing a change in state from 400 k to 800 k
Kitty [74]

Answer:

The correct answer is "430 kJ/kg". A further explanation is given below.

Explanation:

The given values are:

T₁ = 400 k

T₂ = 800 k

The average temperature will be:

= \frac{T_1+T_2}{2}

= \frac{400+800}{2}

= 600 \ k

From table,

At 600 k the C p will be = 1.075

Now,

⇒ The specific enthalpy = Cp(T_2-T_1)

⇒                                \Delta h=1.075 (800-700)

⇒                                      =430 \ kJ/kg
