Taking into account the definition of density, the density of the cubic block of ice is 1.077
In first place, density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is the relationship between the mass of a substance (or a body) and its volume. It is an intrinsic property of matter, since it does not depend on the amount of substance that is considered.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
In this case, you know:
- mass= 1400 grams
- volume= 1300 cm³
Replacing in the definition of density:
Solving:
density= 1.077
Finally, the density of the cubic block of ice is 1.077

Plants
Fungi
Plants are eukaryotic autotrophs (with chlorophyll therefore carrying out photosynthesis, producers).
Fungi are eukaryotic heterotrophs (without chlorophyll) living either as saprophytes; feeding on dead or decayed matter or as parasites.
Plants are the producers in an ecosystem.
Fungi generally are the decomposers of the ecosystem.
Plant cell wall is made up of cellulose.
Fungal cell wall is made up of chitin.
Plants have definite cell wall.
Fungi may be septate or aseptate
Plant cells generally posses single nucleus.
Fungal cell may be uninucleate or multinucleate.
Plant body is differentiated into stem, root and leaf.
Fungal body is filamentous made up of mycelium and hyphae, non-parenchymatous without complex organs or differentiation.
In plants, stored food is starch.
In fungi, stored food is glycogen.
Plants reproduce by seeds.
Fungus reproduce by spores.
Examples:
Mango tree (Mangifera indica), Rose (Rosa indica)
Classification of Plants Groups
Examples:
White button mushroom (Agaricus bisporus); Brewer's yeast (Saccharomyces cerevisiae)

The hydronium ion concentration of a pH = 9.2 of solution is 6.3 × 10⁻¹⁰M.
<h3>How do we calculate pH?</h3>
pH of the solution is define as the negative logarithm of the concentration of the hydronium ion as:
pH = -log[H⁺]
Or [H⁺] =
Given that pH value = 9.2
On putting values, we get
[H⁺] = = 6.3 × 10⁻¹⁰M
Hence required concentration of hydronium ion is 6.3 × 10⁻¹⁰M.

The answer is D glad to help :)<span />
<em>water melts at 32 F and boils at 212 F
if we change these values into Kelvin then
melting point of water is 273.15 K and boiling point is 373.15 kelvin..
for melting it is necessary for ice to get warm so it attains heat 10 F to 32 F...
then ice melts but during this temperature remains constant..
the energy required for melting is 333 kJ/Kg K
then water is warmed at 305 Kelvin.... :)</em>
