Milk (lowest acidity) < Coffee < Orange juice < Soda pops < vomit < Battery acid (highest acidity)
explanation :
pH values of all :
battery acid pH = 1.0
vomit pH = 2.0
soda pop pH = 2.5
orange juice pH = 3.5
coffee pH = 5.0
milik pH = 6.5
pH value is lesser acidity is more . high pH indicate lesser acidic nature
We can use the heat equation,
Q = mcΔT
where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).
Q = 11.2 kJ = 11200 J
m = <span>145 g
</span>c = ?
ΔT = (67 - 22) °C = 45 °C
By applying the formula,
11200 J = 145 g x c x 45 °C
c = 1.72 J g⁻¹ °C⁻¹
Hence, specific heat of benzene is 1.72 J g⁻¹ °C⁻¹.
A solid, a liquid or a gas.
