Answer:
Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering
Explanation:
Answer:
gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Explanation:
a or c becuse it means you should answer it very wiseley
2.5 km is the distance you can travel if a car gets 14 kilometers per liter and have 35 liters of gas.
Total distance traveled in 1 liter = 14 km
Total gas in the car = 35 liters
We have to find how much distance can be covered in in35 liters of gas.
Distance is the length of the path traveled between two points. It is the total movement of an object in a direction. It measures length.
Distance = 35/14
Or, distance = 2.5 km
Therefore, the total distance that can be covered by a car in 35 liters of gas is 2.5 km.

Answer:
<u>Specific heat capacity</u> is the amount of heat required to change the temperature of 1 gram of a substance by 1 degree Celsius
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity.For example,
The specific heat capacity of oil is 1.57 j/g. K and for water is 4.18 j/g.K. So, water take a time to increase its temperature by one degree by absorbing more heat while oil will heat up faster by absorbing less amount of heat.
Consider that both oil and water have same mass of 5g and change in temperature is 15 K. Thus amount of heat thy absorbed to raise the temperature is,
For oil:
Q = m.c. ΔT
Q = 5 g× 1.67 j/g K × 15 K
Q = 125.25 j
For water:
Q = m.c. ΔT
Q = 5 g× 4.18 j/g K × 15 K
Q = 313.5 j
we can observe that water require more heat which is 313.5 j to increase its temperature.
