Answer:
My role models are my parents. They are my pillars of strength. They are my guide and give me the courage to battle obstacles in life.
My mother, being a working professional, manages all her work perfectly and with efficiency.
My father goes to office, but still does not forget to help me with my studies. They always encourage me in every aspect and motivate me even when I do not succeed.
My mother always smiles, no matter what the circumstances are and that gives me the strength and inspiration to face all problems.
My parents have made me understand what life is about and how to find that little ray of happiness in difficult situations.
What I am today and what I will become in future involves the support and affection of my parents. They have made me disciplined, dedicated and sincere.
A role model does not have to be a famous personality. It can be anyone who makes us believe in ourselves.
My parents fill sweetness in my life. From childhood I have learnt everything from my parents.
Not just parents, I also consider my teachers as role models. Even they guide me and show the path of success.
They have turned me into a fighter in the war of life
Answer:
c = 1.61 j/g.°C
Explanation:
Given data:
Mass of oil = 9 g
Heat added = 824 j
Initial temperature = 30°C
Final temperature = 87°C
Specific heat of oil = ?
Solution:
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
ΔT = Final temperature - final temperature
ΔT = 87°C - 30°C
ΔT = 57 °C
Q = m.c. ΔT
824 j = 9 g × c × 57 °C
824 j = 513 g. °C × c
c = 1.61 j/g.°C
