Answer:

Solution given:

specific heat capacity of water [c]4.186 J/g °C

temperature[∆T]=?

mass[m]=3g

heat[Q]=8000J

we have

Q=mc∆T

8000=3*4.186*∆T

∆T=8000/12.558

∆T=637.04°C

<u>the temperature </u><u>change</u><u> </u><u>i</u><u>s</u><u> </u><u>637.04°</u><u>C</u><u>.</u>

The volume of a gas is 650.ml at 1.14celsius what will the volume be at 75.0 Celsius?
Triss [41]

Answer: 42763ml

Explanation:

Using Charle's law

V1/T1=V2/T2

V1= 650ml

V2=?

T1= 1.14c

T2= 75c

Substitute the value

650/1.14=V2/75

Cross multiply

650×75=V2×1.14

V2= 650×75/1.14

V2= 42763.16ml

V2= ~42763ml

A loaf of bread has a volume of 3450 cm3 and a mass of 645 g.What is the density of the bread
zavuch27 [327]
Hi,

The density is given by the ratio of mass to volume, so the density of the bread is 645g/3450cm3=0.187 g/cm^3.

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
