How does the body react when the outside temperature gets too hot

1 answer:

6 0

When temperatures rise, the body reacts by increasing blood flow to the skin's surface, taking the heat from within the body to the surface. This means sweat. ... If, as in the UK, our skin temperature is warmer than the external temperature we are also able to lose heat to the environment, termed 'dry heat loss'.

Given a magnesium value of 4.5mg/dL, what is the result in SI units?

DaniilM [7]

Answer:

$4.5x10^{-5}\frac{kg}{L}$

Explanation:

Hello!

In this case, since the density in the international system of units is given in terms of kg for the mass and L for the volume, we need to perform a process of units conversions from mg and dL to kg and L as show below:

$4.5\frac{mg}d{L}*\frac{1kg}{1x10^6mg} *\frac{10dL}{1L} \\\\4.5x10^{-5}\frac{kg}{L}$

Best regards!

Because water molecules are polar and carbon dioxide molecules are nonpolar,

Gala2k [10]

The correct is D.

Water is a polar molecule and it has polar bonds, which carry partially positive and partially negative charges. This polar bond increases the attraction between molecules of water and thus it requires a greater energy to break the bond between the molecules of water compare to carbon dioxide, which is a non polar molecule. Thus, water has a higher boiling point than carbon dioxide.

.an open flask contains 0.200 mol of air. atmospheric pressure is 745 mmhg and room temperature is 68˚f. how many moles are pres

aleksklad [387]

0.219 moles moles are present in the flask when the pressure is 1.10 atm and the temperature is 33˚c.

What is ideal gas constant ?

The ideal gas constant is calculated to be 8.314J/K⋅ mol when the pressure is in kPa.
The ideal gas law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas.
The combined gas law relates pressure, volume, and temperature of a gas.

We simple use this formula-

The basic formula is PV = nRT where. P = Pressure in atmospheres (atm) V = Volume in Liters (L) n = of moles (mol) R = the Ideal Gas Law Constant.

68F = 298.15K

V = nRT/P = 0.2 * 0.08206 * 298.15K / (745/760) = 4.992Liters

n = PV/RT = 1.1atm*4.992L/(0.08206Latm/molK * 306K)

n = 0.219 moles

Therefore, 0.219 moles moles are present in the flask when the pressure is 1.10 atm and the temperature is 33˚c.
