Answer:
Mendel, Inheritance/Heredity
Explanation:
Gregor Mendel (1822-1884) was an Austrian monk and scientist as stated in this question. He is referred to as the FATHER OF GENETICS due to his immense contributions to the principle of inheritance.
Gregor Mendel via his several works conducted on pea plants was able to demonstrate how traits passed down from parents to offsprings in a process called INHERITANCE OR HEREDITY.
Explanation:
1 Cal of energy is equivalent to 4.184 Joules.
A.
770Cal of energy = 3221.680 joules
Therefore, 780kCal of energy = 3221680 Joules.
B.
3200000 Joules (in 2 s.f).
C.
I000 joules = 1 kJoule
3221680 joules = 3221.689 kJoules.
D.
3200 kJ (in 2 s.f).
Answer:
Mass of the water = 0.1kg is 100g
Explanation:
Mathematically;
Quantity of heat = mass of water * specific heat capacity * temperature change
From the question, we identify the following;
Quantity of heat = 6.3 KJ
1 KJ = 1000 J, so 6.3 KJ = 6.3 * 1000 = 6300 J
Mass of water = ?
Specific heat capacity = 4200
Temperature change is the difference between the final and initial temperature. = 75-60 = 15
6300 = m * 15 * 4200
63 = m * 15 * 42
63 = 630 m
m = 63/630
m = 0.1 kg
