Answer:
Mass = 1.42 g
Explanation:
Given data:
Amount of heat absorbed = 4.56 j
Initial temperature = 29°C
Final temperature = 36°C
Mass of iron metal = ?
Specific heat capacity of iron = 0.46 j/g.°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 36°C - 29°C
ΔT = 7°C
Q = m.c. ΔT
m = Q / c. ΔT
m = 4.56 j / 0.46 j/g°C . 7°C
m = 4.56 j /3.22 j/g
m = 1.42 g
The object with more volume is the inflated balloon
Explanation:
Volume is about how much space an object or material occupies; in this context, if the inflated balloon has the double size of the bag of marbles then the balloon has more volume because this is occupying more space.
Moreover, the volume should not be confused with other factors such as mass or weight because it is likely the marbles weight more but this does not imply the marbles have more volume. Also, the balloon contains gas and gases tend to expand and occupy more space, which does not occur with solids such as marbles because these have a defined volume.
you build them like sandcastles.
you go to the beach, get some sand, put it all together, and

Babies are made! :0
Answer:
<em>Solution:</em>
Explanation:
V1 = 3.00m3
T1 = 150kPa
V2 = 1.20m3
T2 = x
As ,
<u> V1 </u> = <u>V2</u>
T1 T2
<u> 3.00</u> = <u>1.20</u>
150 X
3.00 x X = 150 x 1.20
3.00X = 180
X = <u>180</u>
3.00
<em>X = 60 kPa</em>
B.
Delta G is negative and Delta S is positive.
