Answer:
5.52cm³ of water will rise and might spill over the edge
Explanation:
Use the change in volume of a liquid with changing temperature equation which is written as
ΔV = β x V₀ x ΔT, where β is the coefficient of expansion, V₀ is the volume being submerged and ΔT is the difference in temperature
ΔV = (69 x 10⁻⁶) x (0.1 x 0.1 x 0.1) x (85 - 5)
ΔV = 5.52 x 10⁻⁶ m³
ΔV = 5.52cm³
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis is the right order!
Answer:
ΔT = 76.5 °C
Explanation:
Given data:
Amount of water = 100.0 g
Energy needed = 32000 J
Change in temperature = ?
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
Now we will put the values in formula.
Q = m.c. ΔT
ΔT = Q / m.c
ΔT = 32000 j/ 100.0 g × 4.184 j/g. °C
ΔT = 32000 j / 418.4 j /°C
ΔT = 76.5 °C
Answer:
[H+] =5.62*10⁻¹⁰
Explanation:
pH = 9.25
The formula to find pH of a solution is
pH = -Log[H+]
9.25 = -Log[H+]
Take the anti log of both sides
[H+] = 10⁻⁹.²⁵
[H+] = 5.62*10⁻¹⁰
The concentration of Lithium Hydroxide is 5.62*10⁻¹⁰
Theory. maybe hypothesis.
