Answer:

Explanation:

Total volume of solution = 100 mL .

Total mass of the solution = 100 x 1.01 g

= 101 g

specific heat of solution = 4.184 J/g-°C

rise in temperature = 8.65  °C

heat released = mass x specific heat x rise in temperature

= 101 x 4.184 x 8.65

= 3655.35 J

= 3.655 kJ .

qsolution = 3.655 kJ .

Gas particles are pumped into a rigid steel container at a constant temperature. Which statement describes the change in pressur
Masteriza [31]

Answer:

The pressure inside the container would increase with each additional pump.

Explanation:

  • From the general gas law of ideal gases:

<em>PV = nRT,</em>

where, P is the pressure of the gas.

V is the volume of the gas.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas.

  • As clear from the gas law; the pressure of the gas is directly proportional to the no. of moles of the gas.

<em>P α n.</em>

  • As gas particles are pumped into a rigid steel container, the no. of moles of the gas will increase.

So, the pressure of the gas will increase.

<em>Thus, the right choice is: The pressure inside the container would increase with each additional pump.</em>

Which of these describes something a civil engineer would design?
pishuonlain [190]

Answer:

<em>The correct option is B) a bridge to connect two landmasses over a stretch of water.</em>

Explanation:

A civil engineer is a person who deals with the designing and construction of infrastructure projects like the construction of roads, buildings, bridges, airports, tunnels etc. Civil engineering is one of the most oldest disciplines in engineering and it is broken into many sub-disciplines. A civil engineer might work for a private or a government-based organization. Hence, among the options mentioned in the question, the construction of a bridge is the most likely function of a civil engineer.
