In the winter, a heated home in the Northeast might be maintained at a temperature of 78°F. What is this temperature on the Cels
masya89 [10]

Answer:  25.6^0C,  298.6K

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like ^0C and K  

These units of temperature are inter convertible.

We are given:

Temperature of the gas = 78^0F

Converting this unit of temperature into ^0C by using conversion factor:

^oC=\frac{5}{9}\times (^oF-32)

^0C=\frac{5}{9}\times (78^oF-32)

25.6^0C

Converting this unit of temperature into K by using conversion factor:

K=t^0C+273

K=25.6+273

298.6K

Thus the temperature on the Celsius and Kelvin scales are 25.6^0C  and 298.6K respectively.

Why k has more shielding effect than Na?​
lara [203]

Explanation:

As the charge of all electrons are equal, the repulsive force exerted by each of them is also going to be equal. So, as K has more electrons repulsing its valence electron than Na, it has greater electron shielding.

The mass of a large order of french fries is about 170 G what is its approximate weight in pounds
kap26 [50]

Answer:

             0.374 Pound Approximately

Solution:

Gram and Pound are related as,

1 Gram  =  0.0022 Pound (approximately)

As we are given with 170 g of French Fries, so it can be converted into pounds as,

          1 Gram  =  0.0022 Pound

So,

          170 Grams  =  X Pounds

Solving for X,

                      X =  (170 Gram × 0.0022 Pounds) ÷ 1 Gram

                      X =  0.374 Pound Approximately
