Goal of the planned mission MIRI is "to explore the Kupier Belt".

Explanation:

MIRI, Mid-infrared Instrument, was designed to play an important role in NASA's "James Webb Space Telescope"(JWST).This is a joint project involving the Space Agency  Europe and Canada. This telescope is designed to bring the images of stars and galaxies in infrared light. This grasps a wavelength of  5 to 28 microns. It also has a sensitive dectector allowing to see the red shifted light, stars that are newly formed and the comet that are blur.

Also, to explore the Kuiper belt that is located in the outer solar system that extends from the Neptune to sun. It is believed to be similar to  asteroid belt but 20 times broad and 200 times massive than it.

You are making homemade ice cream and can use either 200 g Ice Melt (CaCl2) or 200 g rock salt (NaCl) to lower the freezing poin
mash [69]

Answer:

Calcium chloride (CaCl2) would help me eat my ice cream faster

Explanation:

Addition of salt to ice melts the lowers the freezing temperature of the ice thus melting the ice easily

Adding calcium chloride to my ice cream would help me eat it faster because the melting point of calcium chloride (772°C) is lower than that of sodium chloride (melting point is 801°C). Calcium chloride would melt my ice cream faster because of its lower melting point

To what family of the periodic table does this new element probably belong
julsineya [31]
<span>Ionization energy (IE) is the amount of energy required to remove an electron. If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).</span>

An ideal gas at a given initial state expands to a fixed final volume. would the work be greater if the expansion occurs at cons
crimeas [40]

Answer:

Constant pressure

Explanation:

At constant pressure,

w = -p\Delta V = -p(V_{f} - V_{i})

At constant temperature,

w = -RT \ln \left(\dfrac{V_{f}}{V_{i}} \right)

1 mol of an ideal gas at STP has a volume of 22.71 L.

Let's compare the work done as it expands under each condition from an initial volume of 22.71 L.

Isobaric expansion

w = -100p(V_{2} - 22.71}); \text{(1 bar$\cdot$L = 100 J)}

A plot of -w vs V₂ gives a straight line (red) with a constant slope of 100 J/L as in the diagram below (Note that w is work done on the system, so -w is the work done by the system). \

Isothermal expansion

w= -8.314 \times 273.15 \ln \left(\dfrac{V_{f}}{22.71} \right)\\\\= -2271 \left( \ln V_{f} -\ln22.71 \right)\\= -2271 \left(\ln V_{f} - 3.123 \right)\\= 7092 - 2271\ln V_{f}

A plot of -w vs V₂ is a logarithmic curve. Its slope starts at 100 J/mol but decreases as the volume increases (the blue curve below).

Thus, the work done during an expansion at constant pressure is greater than if the system is at constant temperature.

Answer: Wind current

Explanation:

The wind current is the main driving force along with the water currents when one reaches to the seashore. The wind currents above surface of water generates due to the evaporation of water.

The strong wind currents can pull any animal or human walking or running near the sea shore. These currents bring the animal or human towards the sea.
