Answer:

Velocity is the speed with displacement .

( Rate of displacement ).

Explanation:

Displacement is a vector quantity, which is the distance traveled in a definite direction.

Speed is the rate of distance traveled and is the ratio of distance to time.

Velocity is the rate of displacement and is given as the ratio of the displacement to the time.

For example if a car is traveling at a speed of 50 kmph, specifying the direction of travel gives its velocity, like 50 kmph towards east or right. Speed is a scalar where as velocity is a vector quantity.

Predict the pressure that would be observed if the container was at a temperature of 1,135 K.
denis-greek [22]

This problem is asking to predict the pressure in the container at a temperature of 1,135 K with no apparent background; however, in similar problems we can be given a graph having the pressure on the y-axis and the temperature on the x-axis and a trendline such as on the attached file, which leads to a pressure of 21.2 atm by using the given equation and considering the following:

<h3>Graph analysis.</h3>

In chemistry, experiments can be studied, modelled and quantified by using graphs in which we have both a dependent and independent variable; the former on the y-axis and the latter on the x-axis.

In addition, when data is recorded and graphed, one can use different computational tools to obtain a trendline and thus, attempt to find either the dependent or independent value depending on the requirement.

In this case, since the provided trendline by the graph and the program it was put in is y = 0.017x+1.940, we understand y stands for pressure and x for temperature so that we can extrapolate this equation even beyond the plotted points, which is this case.

In such a way, we can plug in the given temperature to obtain the required pressure as shown below:

y = 0.017 ( 1,135 ) + 1.940

y = 21.2

Answer that is in atm according to the units on the y-axis:

How much heat is required to increase the temperature of 100.0 grams of iron from 15.0oC to 40.2oC? (The specific heat of iron i
svetlana [45]
The formula you need is: heat= specific heat x mass x ΔT

specific heat= 0.46 j/g-C
mass= 100.0 grams
ΔT= 40.2 - 15.0= 25.2C

heat= (0.46) x (100.0) x (25.2)=  1159.2 joules or 1200 joules (rounded off)
