One gram of glass will rise 20° C when------------calories of heat are applied

Chemistry
1 answer:
astra-53 [7]3 years ago
6 0

Answer:

3.2 Calories

Explanation:

Here we will use a formula

Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass  

As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat  is .16 calories/gm

Incorporating the values of mass (m), temperature(T) and  specific heat (c) in formula.

     calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C

                                                      = 3.2 calories


Hope it helps:)

nlexa [21]
Answer is: <span>concentration of fluoride in the water in parts-per-million is 1 ppm.
</span>Parts-per-million (10⁻⁶) is<span> present at one-millionth of a </span>gram per gram of sample solution, f<span>or example mg/kg.
</span>m(fluoride) = 500 g · 1000 mg/g = 500000 mg.
m(water) = d(water) · V(water).
m(water) = 1 kg/L · 500000 L.
m(water) = 500000 kg.
arts-per-million = 500000 mg ÷ 500000 kg = 1 mg/kg = 1 ppm.

Compound A melts at 801o C and is soluble
Karo-lina-s [1.5K]

Explanation:

Organic compounds are defined as the compounds which contain carbon as their main element. For example, CH_{3}OH is an organic compound.

Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.

As compound A melts at 801^{o}C and is soluble  in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.

Whereas compound B melts at 24^{o}C and is insoluble  in water. This means that this compound has covalent bonding and it is also non-polar in nature . Hence, it is more likely to be organic in nature.

Thus, we can conclude that compound B is more likely to be an organic

compound.
