Answer:
True for water: a. In a phase diagram the solid-liquid coexistance line has a negative slope. d. the solid is less dense than the liquid. f. the molecules are closest in the liquid phase. g. Higher pressure will cause the solid to become liquid.
True for most other substances: b. In the phase diagram the solid-liquid coexistance line has a positive slope. c. the solid is more dense than the liquid. e. the molecules are closest in the solid phase. h. higher pressure will cause the liquid to become solid.
Explanation:
Liquid water is usually more dense than the solid ice. This is in contrast to most other substances. In addition, the phase diagram of liquid water is different from those of other substances because of the signs of their slopes. The presence of high pressure can change ice to liquid water while for other substances the presence of high pressure will change liquid to solid.
False
Explanation:
The geologic time scale which simplifies earth's long history is broad division of deep time. It consists of a large and small divisions.
- The geologic time scale is divided into large broad categories; called eons, eras, period and epoch.
- The scale is merges absolute dating of events that has happened in geologic past and their relative ages.
- Broad categories on the scale are further simplified into smaller units.
- Relative age puts events in the order of their appearance using a couple of geologic principles.

Answer:
d = 0.93 g/cm³
Explanation:
Given data:
Mass of object = 28 g
Volume of object = 3cm×2cm×5cm
density of object = ?
Solution:
Volume of object = 3cm × 2cm ×5cm
Volume of object = 30 cm³
Density of object:
d = m/v
by putting values,
d = 28 g/ 30 cm³
d = 0.93 g/cm³
You are right, it's CA Calcium, 40.08, Group 2 and Row 4.
