Hello!
Take for example the heating of water.
When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.
But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat.
Have a nice day!
Answer:
1.69 × 10² ball bearings
Explanation:
The output of a plant is 4335 pounds of ball bearings per week (five days). The output of the plant per day is:
4335 lb/5 day = 867.0 lb/day
1 pound is equal to 453.592 grams. The mass in grams made each day is:
867.0 lb/day × (453.592 g/1 lb) = 1.911 g/day
Each ball bearing weighs 0.0113 g. The number of ball bearings made each day is:
1.911 g/day × (1 ball bearing/0.0113 g) = 1.69 × 10² ball bearing
Answer:
MgF2 - Salt
H2SO4 - Acid
Explanation:
Arrhenius Definition
Arrhenius acid is a substance that dissociates in water to form hydroxide (H+) ions.
Arrhenius base is a substance that dissociates in water to form hydroxide (OH–) ions.
H+
OH-
S2-
O2-
MgF2 - Salt as no Hydrogen
H2SO4 - Acid as converts to HSO4- and H+ upon dissociation in water.
