If the pressure of 125 cm3 of nitrogen gas at 100 °c decreases from 885 torr to 225torr, what is the final volume? assume temper
navik [9.2K]
Suppose the Gas is acting ideally, Then, According to Ideal Gas Equation;

                                               P₁ V₁  =  P₂ V₂    ----- (1)
Data Given:
                  P₁  =  885 torr

                  V₁  =  125 cm³

                  P₂  =  225 torr

                  V₂  =  ?

Puting values in eq, 1;

                                     V₂  =  P₁ V₁ / P₂

                                     V₂  =  (885 torr × 125 cm³) ÷ 225 torr

                                     V₂  =  491.66 cm³

Is NaCH an element ? why or why not?
Mandarinka [93]
I believe you mean NaCI*, (sodium chloride) . Sodium Chloride is not an element, it is known as an ionic compound, reason being because it forms an ionic bond with Na and CI.

3. Unlike global winds, local winds (select the two answers that are correct)
Viktor [21]

Answer:

Small-scale convection currents arise from uneven heating on a smaller scale. This kind of heating occurs along a coast and in the mountains. Small-scale convection currents cause local winds. Local winds blow over a much smaller area and change direction and speed over a shorter period of time than global winds.

Maybe that will help you answer the question.

A fuel was burned for 5 min, increasing the temperature of 10.0 g of water with a density of 1.00 g/ml by 9.0 oC. The fuel relea
jekas [21]

The fuel released 90 calories of heat.

Let suppose that water experiments an entirely <em>sensible</em> heating. Hence, the heat released by the fuel is equal to the heat <em>absorbed</em> by the water because of principle of energy conservation. The heat <em>released</em> by the fuel is expressed by the following formula:

Q = m\cdot c \cdot \Delta T (1)

Where:

  • m - Mass of the sample, in grams.
  • c - Specific heat of water, in calories per gram-degree Celsius.
  • \Delta T - Temperature change, in degrees Celsius.

If we know that m = 10\,g, c = 1\,\frac{cal}{g\cdot ^{\circ}C} and \Delta T = 9\,^{\circ}C, then the heat released by the fuel is:

Q = (10\,g)\cdot \left(1\,\frac{cal}{g\cdot ^{\circ}C} \right)\cdot (9\,^{\circ}C)

The fuel released 90 calories of heat.

You want to minimize an objects thermal energy loss on a cold day. How does heat energy transfer affect thermal energy loss?
san4es73 [151]

Answer:

4- A material that transfers heat energy more easily than another material will experience a greater rate of thermal energy loss than an object that does not transfer heat energy easily.

Explanation:

Thermal energy loss has to do with loss of heat energy by a body to another body or its environment. The aim of the process is usually the attainment of thermal equilibrium between the body and its environment.

On a cold day, a material that transfers thermal energy more easily will loose thermal energy faster than an object that does not transfer thermal energy. The rate of heat transfer of a body determines its rate of loss of thermal energy.
