What factors influence heart rate?
Sex - women have faster HR than men Age - HR gradually decreases with age, then increases when advancing old age Body temperature - HR generally increases of 7-10 beats per min (bpm) for each degree of temperature elevation Digestion - HR increases when metabolic rate increases Pain - increases HR Exercise - increases HR
What does your heart do when your heart rate increase?
The heart rate increases because of your bodies cells need more oxygen during activity. Nerves in the heart make the pacemakers fire electrical impulses faster because they release epinephrine and neropinephrine and thus the heart rate increases.
What happence to your pulse rate when you exercise?
when you exercise, your heart rate increases. the more explosive and intense the exercise, the higher the rate will go. As with any muscle in the body, exercise makes it stronger. a stronger heart allows for more blood and oxygen to circulate with each pump resulting in your heart rate lowering not only during exercise but in daily life. a lower heart rate means your heart does not have to work as hard and thats a good thing !!!
Each time the heart beats what does it do to blood-?
It simply keeps it circulating throughout the body. Your heart is the one muscle that works all the time and keeps you alive. Your mind and your heart basically depend on each other. The mind tells the heart when to beat, and the heart pumps oxygen-rich blood to the mind. But really all the heart does is allow blood circulation through your body. Best to eat healthy to avoid disturbances in its work, which are usually lethal. (Life threatening.)
Each complete heart beat is called what?
cardiac cycle
What does each degree on the celsius scale represent?
The Celsius scale was created so that 0 was defined as water's freezing point and that 100 was defined as water's boiling point (at 1 ATM of preasure). /\ (that means "delta" or "change of/in") /\ 1C = /\1.8F So if the temp increases by 1 degree celsius, then that is a 1.8 degree increase Fahrenheit .
What is 1 degrees Celsius in Kelvins?
A Kelvin (K) is a degree of temperature, equal in size to a Celsius degree (C), on a scale that begins at absolute zero. -273.16° C = 0o K (absolute zero) Because each Celsius degree equals one Kelvin degree, 0o C = 273.16o K. Add 274.16o degrees to each side of the equation, then 1o C = 274.16o K.
Which is smaller increase in temperature a 5 Fahrenheit increase or a 5 Celsius increase?
A 5 Celsius increase is smaller than a 5 Fahrenheit increase. This is because each Celsius degree is larger than each Fahrenheit degree.
What happens to the speed of sound due to increase in temperature of the air?
The average speed of sound increases by approx 0.6 metres/second for an increase in temperature of each degree Celsius.
Why does the clinical thermometer show degree Fahrenheit when India has adopted degree Celsius?
Each and every thermometer has both the scales that is Fahrenheit and Celsius both. Celsius is not specific for India. You can use the scale that you are comfortable with.
Is one kelvin unit equivalent to 1 Fahrenheit?
No.1 Kelvin degree is equal to 1 Celsius degree. Kelvin starts at - 273.15 oC but each degree has the same size Kelvin and Celsius.
Is -40 degree Fahrenheit cooler than -40 degree Celsius?
0
Which is warmer 1F or 1C why?
1°C is warmer than 1°F. This is because the Celsius scale has a larger degree interval than the Fahrenheit scale, with each degree Celsius representing a greater change in temperature than each degree Fahrenheit.
Are celsius scale degree larger than Fahrenheit degree?
A "degree" on the Celsius scale is larger than a "degree" on the Fahrenheit scale. There are 100 equal intervals (degrees) between 0 °C and 100 °C, the freezing and boiling points of water. There are 180 equal intervals between those same temperatures on the Fahrenheit scale (32 °F and 212 °F). That makes each Celsius degree 1.8 times as large (wide) an interval as the Fahrenheit degree. This is the basis for the "9/5" an "5/9" fractions in the conversion formulas (9/5 = 1.8). Some conversion formulas omit the fractions in favor of multiplying or dividing by 1.8, which is a single step. (see related questions)
What represents degree in thermometer?
Degrees on a thermometer represent temperature, which is a measure of the average kinetic energy of particles in a substance. As temperature increases, the particles move faster and the thermometer reading goes up. Each degree on a thermometer typically represents a specific amount of temperature change, such as one degree Celsius or Fahrenheit.
What is -1 degree Celsius in Fahrenheit?
The temperature 1 degree Celsius is 33.8 degrees Fahrenheit.The conversion formula is °F = (°C * 9 / 5) + 32°Degree Intervals in Celsius compared to Fahrenheit : 1 "degree" Celsius = 1.8 "degrees" FahrenheitA "degree" on the Celsius scale is 1.8 times as large as a "degree" on the Fahrenheit scale. A temperature difference on the Fahrenheit scale will be 1.8 times as large a value as the same temperature difference on the Celsius scale. Celsius uses larger intervals for each degree.Example : The freezing point of water is 0 °C and 32 °F. When the temperature increases to 10 °C, the equivalent Fahrenheit change is 18 degrees, to 50 °F.(see related questions)33.8 F
Each degree on the Kelvin scale equals?
The relationship between Kelvin and Celsius scale is K=C+273. 15. Where K is Kelvin temperature and C is Celsius temperature. Each degree on the Kelvin scale equals the same degree in Celsius scale differing only in the zero value. The freezing point of water and absolute zero are the zero values of Celsius and Kelvin scale respectively.
