Dr. Arenas is a scientist who has been trying to determine if increasing pressure will increase the sound that occurs when two c

hemicals explode. She measures the volume of the sound that occurs at the minimum pressure at which the explosion will occur. She then increases the pressure and measures the volume of the explosions that occur. What kind of investigation is the scientist conducting?

Lily took 6 hours to complete a journey at an average speed of 58 km/h. For the first 4 hours, she travelled at an average speed
arlik [135]

Answer:

92km

Explanation:

Given parameters:

Duration of the journey  = 6hrs

Average speed  = 58km/hr

  Now, let us find the total distance of the journey;

 Distance  = Speed x time

  Distance  = 58 x 6   = 348km

So;

 Average speed for the first 4hrs  = 64km/hr

                                               Time  = 4hrs

     Distance  = 64 x 4 = 256km

For the rest of the journey, the student will cover;

                               = 348km  - 256km

                               =  92km

a college student produces about 100 kcal of heat per hour on the average what is the rate of energy production and joules
Bond [772]

Given:

Amount of heat produced = 100 kcal per hour

Let's find the rate of energy production in joules.

We know that:

1 calorie = 4.184 Joules

1 kcal = 4.184 Joules

To find the rate of energy production in Joules, we have:

\begin{gathered} Rate=100\ast4.184 \\  \\ \text{Rate}=418.4\text{ KJ/hour} \end{gathered}

Therefore, the rate of energy production in joules is 418.4 kJ/h which is equivalent to 418400 Joules

ANSWER:

418.4 kJ/h

7. How much thermal energy is absorbed when 10.0 g of ice at 0.0 degrees C changes phase to liquid water at 0.0 degrees C? The m
Nesterboy [21]

Answer:

3.34 kJ

Explanation:

FIrst of all, we need to calculate the number of moles corresponding to 10.0g of ice. This is given by

n=\frac{m }{M_m}

where

M_m = 18.02 g/mol is the molar mas

m = 10.0 g is the mass

Substituting

n=\frac{m}{M_m}=\frac{10 g}{18.02 g/mol}=0.555 mol

Now we know that the heat of fusion is

H_{fus}=6.01 kJ/mol

so the thermal energy needed to fuse the ice is

Q=n H_{fus} = (0.555 mol)(6.01 kJ/mol)=3.34 kJ
