If sand has a specific-heat capacity of 835 jkgC then how much energy must be added to a 2 kilogram pile of it to increase its temperature from 40 C to 50 C?
Q = m c ΔT Q = energy m = 2 kg c = 835 J / (kg C) ΔT = 10 C Q = 2 kg * 835 J / (kg C) * 10 C Q = 16700 J
How much heat is necessary to change 10 g of ice 10C?
The specific heat capacity of ice is 2.09 J/g°C. To calculate the heat required to change 10 g of ice by 10°C, use the formula Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the temperature change. So, Q = 10g * 2.09 J/g°C * 10°C = 209 J.
If the charge of a body is 3.45 x 10-17 C how many electrons are present?
To find the number of electrons present, you can use the formula Q = ne, where Q is the charge, n is the number of electrons, and e is the elementary charge (1.6 x 10^-19 C). Substituting the values, n = Q/e = (3.45 x 10^-17 C) / (1.6 x 10^-19 C) ≈ 215.625. So, there are approximately 216 electrons present.
How do you calculate q values?
Q value is calculated by taking the difference between the total mass-energy of the reactants and the total mass-energy of the products in a nuclear reaction. The formula for calculating Q value is: Q = (mass of reactants - mass of products) * c^2, where c is the speed of light in a vacuum (3.00 x 10^8 m/s).
How much heat is given off when 10 grams of water are cooled from 50 C to 40 C?
To calculate the heat given off, you would use the formula Q = mcΔT, where m is the mass of the water (10 g), c is the specific heat capacity of water (4.18 J/g°C), and ΔT is the change in temperature (50°C - 40°C = 10°C). Plugging the values into the formula, Q = 10g * 4.18 J/g°C * 10°C = 418 J. Therefore, 418 joules of heat are given off when 10 grams of water are cooled from 50°C to 40°C.
What is a algebraic expression for 10 plus q?
It is simply: 10+q
Q squared plus 20 q plus c?
I'm not exactly sure what you mean by this, but if you'd like to know how to do this in C here: q ^ 2 + 20 q + c
There are two Q's in a C What does Q and C stand for?
two quavers in a crotchet
How many KJ is required to heat 10 kilogams of water from 10 degrees C 110 degrees c?
q(Joules) = mass * specific heat * change in temperature ( 10 kg = 10,000 grams )q = (10,000 g)(4.180 J/gC)(110o C - 10o C)= 4180000 Joules (1 kj/1000 J)= 4.2 X 103 kilojoules================
What are the notes for jingle bell for alt sax?
The notes for "Jingle Bells" on the alto saxophone are typically in the key of C major. The main melody consists of the notes C, D, E, F, G, A, and B. The song is usually played in a simple and straightforward manner, making it accessible for beginners. It's a great piece for practicing basic saxophone techniques such as articulation and phrasing.
Determine the field strength E experienced by a test charge q if a charge of 1.0 x 10-6 coulombs is placed on q and a force of 6.2 N is applied.?
The field strength experienced by the test charge q can be calculated using the equation E = F/q, where E is the field strength, F is the force applied, and q is the test charge. Plugging in the values, we get E = 6.2 N / (1.0 x 10^-6 C) = 6.2 x 10^6 N/C.
How much heat in KJ must be transffered to 10kg of air to increase the temp from 10 Celsius to 230 Celsius at the pressure constant?
The specific heat capacity of air at constant pressure is 1.005 kJ/kg°C. The heat transferred can be calculated using the formula Q = m * c * ΔT, where Q is the heat transferred, m is the mass of the air, c is the specific heat capacity of air, and ΔT is the change in temperature. Plugging in the values, Q = 10 kg * 1.005 kJ/kg°C * (230°C - 10°C) = 4,550 kJ.
