A 250-mL glass bottle was filled with 242mL of water at 20°C and tightly capped. it was then left outdoor overnight, where the a

verage temperature was -5°C. predict what would happen. the density of water at 20°C is 0.998g/cm^3 and that of ice at -5°C is 0.916g/cm^3.

Answer:

The glass bottle will get crack.

Explanation:

Volume of the glass bottles,V = 250 mL

Density of water at 20°C  = 0.998g/cm^3

Mass of water in bottle = M

Volume of water at 20°C ,V' = 250 mL (1cm^3= 1 mL)

V>V'

Density=0.988 g/cm^3=\frac{M}{242 cm^3}

M = 239.096 g

Since mass remains constant, the mass of liquid water will be equal to mass of water when freezes

Density of ice at -5°C = 0.916g/cm^3

Volume of the ice at  -5°C= V''

Density=0.916 g/cm^3=\frac{239.096g}{V'}

V''=261.0218cm^3=261.0218 mL

V''>V>V'

As we can see that volume of water has expanded on freezing and exceeded the volume of the glass bottle. This expansion will result in breaking or cracking of a glass bottle.

If I have 2 liters of gas held at a pressure of 78 atm and a temperature of 900 k, what will be the volume of the gas if I decre
dangina [55]

Answer:

V2 = 2.88L

Explanation:

P1= 78atm, V1= 2L, T1= 900K, P2= 45atm, V2=? T2= 750K

Applying the general gas equation

P1V1/T1 = P2V2/T2

Substitute the above

(78*2)/900= (45*V2)/750

V2= (78*2×750)/(900*45)

V2= 2.88L

The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.

Lilit [14]

Answer:

#1

Heat transfer occurred in the room through radiation

This is where heat is transmitted through vacuum or an empty space from a point to another.

#2

From the furnace, the air molecules nearer the region gained higher kinetic energy hence colliding with other molecules in the room. This causes a positive temperature gradient which causes an increment change in temperature in the room.
