Answer:
1.50 cal
Explanation:
Given data:
Mass of water = 300 g
Initial temperature = 20 °C
Final temperature = 25 °C
Calories needed = ?
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
Solution:
ΔT = T2 - T1
ΔT = 25 °C - 20°C
ΔT =
Q = m.c. ΔT
Q = 300 g . 4.18j/g. °C . 5°C
Q = 6270 J
J calories:
6270 / 4184 = 1.50 cal
Answer:
Maintenance of ionic balance
Explanation:
Synovial fluid:*A fluid that lubricates joints and prevents two cartilage caps from rubbing together*. Small sacs filled with Synovial fluids are called *Bursae*, they help *reduce friction in the joint*.
Functions of Synovial fluid include:
1)Lubrication of articular surface*
2)Nutrient distribution*
3)Shock absorption*
4)Waste disposal*
Note that Maintenance of ionic balance is not a function of Synovial fluid.
